J&L Mark 5 Specialty Folder Gluer

Electronic Variable Speed Folding Belts 

Occasionally, boxes are not cut square in the diecutter, causing a skew in the manufacturer's joint when the box is folded. By varying the speed of the left- or right-hand upper folding belt, additional pressure can be exerted on the panel during the fold to correct die cut deficiencies. By allowing the operator to electronically vary the speed of the folding belts from the operator station, it's not necessary to stop the machine or enter the hazard area while the machine is running boxes to make a folding belt speed adjustment.

 

Small Box Tooling-

Regardless of the width of the J&L purchased, all sizes run the same minimums, allowing the customer to match the J&L width to the largest die cutter in the plant. For customers who tend to run smaller box sizes, the Small Box Tooling Kit simplifies smaller boxes set-ups and allows easier folding and gluing of the smaller panels. Full Flap Final Fold For sleeves and boxes with narrow minor panels, it may be necessary to fold the major panel completely over to the far end of the box.

 

The Full Flap Final Fold - This option allows the upper belt on one side to be shortened, making room for the panel to fold completely over to the far end of the box. 

 

Compression Exit Hold-Down Rods

Depending on flute size and die cutting quality, some smaller box styles may have residual memory in the folded scores, causing them to pop open when exiting the upper compression belt. When these boxes pop open, the glue integrity is lost and the shingled stream is generally broken, creating a gooey mess. The Compression Exit Hold-down Rods control the shingled stream by continuing to exert downward pressure on the shingle until the boxes reach the bundling operator.

 

Drop in Carrier Belt 
This feature provides additional support and drive to the box during front folding of high-width-to-length-aspect ratio boxes.

Enhancements 

 

Openness and Accessibility
As with its predecessors, the Mark 5 architecture provides fantastic visibility and accessibility for operators. Free of doors, windows and mechanical guarding, the open architecture offers the best sightlines in the industry, allowing the operator to visually monitor production and see trouble before it shuts down the machine. Each module has been engineered to provide the operators with the maximum amount of room to set-up tooling. Moving large pieces of tooling in and out of a module is a breeze. Safety rated light curtains prevent entry into hazardous areas while the machine is in production.

 

Fast Set-ups
When it comes to Specialty Folder Gluers, auto-set doesn't necessarily 
mean faster set. For most specialty boxes auto-set means slow set. 
This is not the case with the Mark 5. Unencumbered by lead screws, tooling collisions and repeated jogging of motors, plus all the other gyrations that so-called "auto-set" machines require to adjust the carrier rails, the Mark 5's open design allows operators to quickly adjust tooling and set-up the module correctly the first time. Once set, the operators can jog a set-up box through the module, then move on to the next module. 

 

Base Configuration
The Mark 5 is available in six sizes ranging from 80" up to 190" in width. The base configurations of all machine sizes run Straight-lines, Lock Bottoms, Tubes, Four-Corner, Infold and Outfold trays. Boxes can be over-stacked or under-stacked in the compression section. To accommodate stacking of longer boxes, the compression section is designed to be mobile and can be moved away from the main machine by the operator.

 

Controls Longevity
Mechanically robust enough to run for decades, the Mark 5 Electronic Controls have been specified and selected to ensure supportability well beyound the average life of most electronic components today. This means backward compatible updates, replacement component availability and true supportability to match the projected mechanical life.

 

Box Ejector Module 
The Box Ejector Module is designed to interface with all of today's inspection and quality-control systems. When a box is flagged as having a defect, the box ejector will divert that box out of the flow, negating the need for the bundling operator to sort and remove it.

 

Crush Roller Module 
The Crush Roller Module passes each folded box through an adjustable pressure nip point. The nip point utilizes two chromed rollers, with operator adjustable nip pressure, to flatten the boxes prior to entering the compression section. This allows a more dense compression shingle, higher speeds and ultimately flatter bundles to the end user.

 

Tooling Module 
The Tooling Module contains a set of adjustable 90" long carriers that present the box for labeling, taping, and complicated prefolding. As the industry moves toward shelf-ready packaging and this process becomes more complex, the Mark 5 stands ready with a flexible design able to accommodate updates and additions.

Tanabe Trifeeder Module 
As with previous generations the Mark 5 interfaces very well with the Tanabe Trifeeder. The roll in/out option of the Tanabe Trifeeder allows offline set-up while the Mark 5 can be running traditional specialty jobs.
