KL FPS 300

Hot-melt station

• Fixing the single thread chainstitch seams and sealing the penetrated needle holes
• Two independently operating glue stations with 12 heatable application nozzles, individually switchable in 8 glue heads as required
• Electromotive height adjustment of the glue heads to the exact material thickness; reproducible by device control or product parameters
• Automatic, sensor-controlled hot-melt feeding
• Proportional glue supply adjustment (to material and speed) in automatic mode – adjustable on the control panel
• Width of glue path 8 mm
• Glue head distances can be individually adjusted in height
• Material transport rollers can be adjusted electro-motorically to the individual material thickness
• Free programmable hot melt interruption at the  (at the beginning and at the end of the pocket)
• Blower unit for fast cooling of the hot glue application
• To avoid thermal damages to the filter fabric during stop-mode, the glue heads lift is programmed

Side-seam sewing station

• Movable Pegasus 4-thread  double needle overlock sewing machines (left/right) for manufacture of filter pockets with tapered or straight side seam (electro-motorically controlled, corresponding to the speed of the unit)
• The side seam sewing machines are rotatable - for the production of filter pockets with radii on the side seam
• Sewing speed: approx. 6,700 s.p.m.
• Thread movement monitoring of the 4 threads
• Material transport rollers can be adjusted electro-motorically in height to the individual material thickness
• Synchronization of the material feed and the sewing speed of the sewing machines
• The sewing contour (tapered style) is freely programmable and reproducible via parameters
• Continuous edge trimming (right/left) by the knifes, integrated in the overlock sewing machines (= pocket width)

Remark:
Due to the newly developed, moving high-speed cutting system, meltblown material (WITHOUT pre-filter) can be cut to length without welding of the cutting edges

Bottom-seam station with Pegasus Overlock machines

Outfeed conveyor for a fast removal of the cut-to-length filter pockets from the cutting system area with feed to the double-bottom seam sewing station and the subsequent stacking device on both sides

 Sewing machine (Standard):

• For efficient closing of the cut-to-length filter pockets at the bottom of the pocket with TWO transfer devices for feeding the filter pockets from the outfeed conveyor of the cutting system to the respective bottom seam sewing station
• TWO right-hand Pegasus 4-thread overlock sewing machines with top feed
• TWO thread guide control units for 4 threads
• TWO transport belt systems for pocket feed through the overlock sewing machines
• TWO electropneumatic warp scissors, integrated in overlock sewing machines

Double bottom seam:
Tapered double bottom seam, cut to the desired size of the pocket by the overlock machines of the bottom seam station (depending on the orientation of the b) to the right or to the left side of the machine.

Stacker device (Option)

• Discharge device (from double bottom seam sewing station) of the manufactured filter bags by means of gripping device for filter bags
• Lowerable stacking device with stack height monitoring by means of a photocell or manufactured bag
• stacks defined via preset number of bags
• Conveyor belt with timing and limit switch

Further components

• Compensator for continuous processing while changing the material
• Unwinding system with roll lifting device for up to 4 material rolls
• Inkjet printer for customer-specific imprinting in 12 mm or 24 mm print width during the production process (option)
• Suction device for removal of cutting waste from the overlock machines at the side-seam station and at the bottom-seam station (Option)
• Rewinding station for the production of roll material (option)
• Corner cutting device at the pocket opening, integrated in side seam station (option)
