Infinite Variable Servo Trim

• Allows your trimmer to trim an unlimited variety of books at the same time
• Unlimited range and speed. 
• Includes built in selective jogger control -no additional selective signals required
• Includes built in Selective TQM. Set tolerances on the face trim and skew independently per book
• Easy to use touch screen for quick multiple book setups. 
• Save and Recall Books at any time. 
• A pair of tall, robust backstops move to set books on-the-fly, at full trimmer speed. For example, one book could be trimmed at 9.25" wide, and the very next one behind it could be trimmed at 5" wide. Full accuracy is always realized even if the back stops move 0.01" or 5.5".  
• Independent book settings allows operators to customize trim the length and skew for each book while not affecting the others.  Slight trim errors that were not worth stopping the line earlier can now be compensated for instantly.
• Make-Ready for the entire setup is made in seconds with the touch screen, saving you time!
• The Backstop system is very robust, has less mass than the original mechanical backstop system it replaces, and will provided gainful operation for many years. Available on all HT trimmers.

More information:

LMI Selective Trim / Variable Trim

Allows multiple face cut dimentions to be used in the trimmer at the same time, each with their own spine to face width and their own skew. For example, a 9" book and a 8" book can be co-binded and selectively trimmed in the trimmer accurately at full speed.  Unlimited Trim swing between books. Unlimited skew. Robust and reliable. You only need to supply the signals to the trimmer from your controller regarding which book it's cutting.

Infeed Bearing Roller Upgrade

Replaces the failure prone grease tube and bushing rollers over to a solid shaft and bearing mounted rollers.

- Perminent fix to the chronic wear rollers

- Reduces belt breakage from the stitcher to the trimmer infeed

Heavy Duty Jogger

(Bolt-on Upgrade) This upgrades the HT trimmer's original flimsy jogger to a more robust, heavy duty jogger. While the plate and contact spring is the same (what the book feels) the guiding and actuating mechanism is greatly improved. Jogger is now simpler, more rugged, and operates on linear bushings. Actuator arm is fully supported on two ends via a yoke, resulting in a firm, square, operation that will far outlast the original jogger. Remember the jogger plays a critical roll in the squareness of the book.

HT15 Trimmers, Left Hand Jogger, use kit # HT30A177LM

HT15-V Trimmers, Left Hand Jogger, use kit # HT30A254LM

HT15-V Trimmers, Right Hand Jogger, Use kit # HT30A238LM

HT18 Trimmers, Left Hand Jogger, use ki t# HT30A257LM

HT20 Trimmers, Left Hand Jogger, use kit # HT30A253LM

Selective Jogger

Allows jogger to jog two (or more) different size books, or one book with two different Head/Foot cut-off sized signatures. Operator pre-sets the second book jogged setting (say, 3/16" wider for a certain selective sig) and the jogger will selectively jog to the proper dimension for the proper book. 

* Specify Trimmer type, Left or Right hand side jogger,  1 or 2 or 4 position jogger, Type of transport, VTB-III equipped yes/no, and mesurments for the position points.

LMI Stationary Jogger

Fine tune stationary jogger on the opposite side of your primary jogger, allows quick and simple adjustment while maintaining parallelism.  Hard coated plate for long lasting durability.

Reverse Jogger

Reverse Jogger based on our Heavy Duty Jogger. Available on all HT trimmers. Please Specify type. (Shown is an HT-15V trimmer)

Chip Gate cross bar hold-down

Eliminates the crossbar bolted on the chipgate. Our crossbar is mounted firmly to the infeed, releaving the chipgate from the extra moving mass. Based on the HT-151, our cross bar is positioned near the front clamp and outfitted with flaps and teflon guides to keep the book down during the critical infeed lug to pusher finger tranfer, and forces the book under the clamp. Extra mounting holes to bolt on anything you can dream up to further aid in jam detection, and prevention.

Side Knife Upper Support Bar

Prevents the lower side knife casting from deflecting inward -the leading cause of sloppy side knife guides. Features half-moon cut-out for T-handle Allen's to allow operators to quickly access the side knife clamps without having to use ball-ends (Also available on our lower support bars).  After straightening your housing, bolt these bars in for maximum support. "Living" locator feature prevents loss of location even when the bar is removed and replaced.

Bedplate mounted infeed guides

Replace your top rail mounted infeed guides with this surperior design. Our hard annodized aluminum guides feature a wide mouth with a tapered guide blade to eliminate tape. These guides mount directly onto the bead plates via large hand knobs. No more vertical brackets and loose rivets to hassle with.

HT-15 Trimmers: Use kit number HT30A394LM to work with a stitcher, or HT30A395LM to work with a Universal Shuttle Hopper.

HT-18 or HT-20 Trimmers: Use kit number LMI-028 to work with a stitcher.

Front Knife Beam Clamp

Replace your old style rack and pinion clamp with this billet aluminum beam clamp. The clevises clamp permanently onto the clamp posts while the clamp independently adjusts via the two mounting bolts -the same style used on HT-20's.  Available on Reverse Knife HT-15's, also available on HT-15V where only the beam clamp is used.

Chip Gate Upgrade

(Bolt-on upgrade) Upgrades the old V-roller chip gate carrier assembly to linear bearings. New system rides on horizontal linear shafts through oiless, self-aligning bearings. Results in a much more stout chip gate, and fewer parts to wear.

Available in ~HT-15V, ~HT-18, ~HT-20, ~HT-151

HT-15V trimmers, use kit # HT30A235LM

HT-18 trimmers, use kit # HT30A236LM

HT-20 trimmers, use kit # HT30A236LM

HT-151 trimmers, use kit # HT30A237LM

High Strength Draw Links

Sporting more than twice the tensile strength of your origional drawlinks,  Our new links are made from aircraft grade solid billet aluminum. Extra metal was added in the bolt cap areas where cracks and breaks typically occurs. Also features longer threaded wells for the bolts. Higher tensile strength better captures the bearing and prevents 'slap' which also plagued the old cast drawlinks. Especially suited for HT20 trimmers, HT-15 "thick book" (modified for 1" books), and HT-151's. 

Backbone Skiver (spine slitter)

Eliminate "Dog Ears" with this Bolt-on upgrade. Skiver addresses the area of thicker square-back books going though the side knives of the HT-trimmer. Our system has a course adjust and a fine adjust that can accurately position the blade to the book. The dual use blade, ramps to the book and registers itself up to 1/8" while cutting the backbone. Blades can be rotated to double up on life.

HT Anti Surge Infeed

Eliminates the infeed chain surging that plagues HT trimmers. Gives the book a smooth transition from the infeed chain lug to the pusher lug resulting in better trim squareness and fewer front knife jams. Available in all HT trimmers.

HT15 Trimmers, use kit # HT30A136LM

HT18 Trimmers, use kit# HT30A155LM

HT20 Trimmers, use kit# HT30A155LM

Billet Infeed rear support

This rear support never cracks or breaks. It also features non-fade away sprockets that eliminates timing and flipping the lugs back up when reversing the trimmer. A large cutout for extra clearance of the infeed chain, preventing the chain from wearing on your very-expensive cast aluminum pusher actuator arm.

HT-15 PUSHER HANDLE KIT

Bolt-on upgrade. Allows make-ready and fine adjustments of the pusher lugs On-the-Fly.  ELIMINATES HAMMERS.  The Heavy duty 'cheater' knob latches out for slewing the pushers during makeready, then folds away for fine tuning during run.

Chainless infeed drive

Drives the entire infeed seprately from the trimmer, eliminating the crankshaft to infeed drive chain. Uses a direct belt drive from the stitcher (in Saddle systems or the line shaft drive in perfect bind systems). compatible with or without flywheels, and keeps the infeed lug to pusher relationship tight. Available on all HT trimmers. 

Add the LMI anti-surge kit for further elimination of internal chain, gear, and lube systems and enjoy better book handling.

Front Knife and Clamp Upgrade

Replaces the hideous front clamp multi-linkage system in the HT-15 trimmer to a single link direct connection from the clamp to the lower camshaft. This greatly reduces clamp slop, allows the clamp to raise higher resulting in fewer knife jams, eliminates the chip gate cams, and greatly enhances performance. NEW Upper and Lower knife housing castings, NEW lower camshaft cams that allow the clamp to raise high, then after the spine of the book passes through, the clamp settles down to just over the book, then quickly clamps down at the exact position. NEW front knife beam clamp with hard coated clamp pads. Also included is the heavy duty Chip gate round linear bearing frame rail system, and our new solid aluminum rear infeed support frame.

Outfeed delivery extension kit

• Extends the delivery chains to the trimmer's end frame. Helps with delivery to downstream equipment
  
• Hard Annodized bed plates with heavy duty side guides.
• Fits all models of HT trimmers
  

Intelligent Airblast

Works with the front knife airblast system. The advantage of the intellegent system is that it automatically cuts off the airblast after 5 seconds of duration. This is handy in saving energy and  noise when stopping the trimmer in a knife-downaward position. Most improtantly, it ensures the operator does not 'temporaily' close the trimmer's blast supply valve and then forgetting about it (which causes a chip gate jam)

    Available on all HT trimmers.

LMI Shear Pin Detector

Our detector features a flexible rat tail jam switch with a reset button. Will not be bent nor tweaked out of calibration by trimmer guard removal, nor mangled by a maintenance man's boot when working on the trimmer.  Also includes an upgraded clutch mounted kick-out flag. The new shape guarentees a large, parallel surface to be presented to the detector at any speed. Includes all mounting hardware.

HT Trimmer Guard (Gull Wing)

Gives the operator excellent access to the trimmer without the restrictions of older guards. Effortlessly open anywhere with powered lift assist. Works with taller operators and offers better visibility and noise reduction. Front and side knife housings can be lifted off without removing the guard support.
