MACHINE COMPONENTS & CONSTRUCTION AUTOMATIC FEEDER
- Designed for stacking Max. ream of 5,000 paper sheets (Max. 120gsm basis weight)
- Feeding section has been developed for also utilising laminated or coated paper. When paper is coated with PP, the overlapping width of the tube and that of the bottom should not be coated for proper and firm pasting.
- Paper sheets are fed one by one by the usage of automated vacuum (suction) - cups.
- Equipped with the double-fed detector.
- The Handle Making Unit incorporates two paper roll stands.
- The loop-shape for twisted handles are formed by a privileged sliding rail
mechanism.
- Easy de-coupling from the mainline in order to produce bags without handles.
HANDLE PATCH ATTACHING UNIT
- By the utilisation of a rotating finger gripping mechanism, handles are attached to the paper sheet.
FORMING STATION
- Paper Sheet creased, folded, longitudinally pasted and pressed in order to form the tube with the gusset on the sides. The folding and creasing are performed by guide plates.
- Designed to avoid tube jamming.
- Provision for easy size change.
TUBE FEEDING UNIT
- Longitudinal glue is completely penetrated on the side seam portion of the bag by a pressing device.
BOTTOM FORMING UNIT
- Bottom Opening Section includes a vacuum cup and vacuum holes on the sides for gripping the bag bottom. Two side fingers, each oriented by two cams (one for horizontal, one for vertical movement) also grab the bottom on sides in order to enable precise bottom forming.
- Vacuum holes, centre finger, middle gripper jaws and side fingers on the main drum grip the counter bottom flap for proper bottom forming.
- Bottom Glue Tank can be dismantled easily out of the main body for cleaning and maintenance purposes.
- Continuous agitation of bottom glue provided to avoid glue from drying.
DELIVERY STATION
- Equipped with a digital bag counter. The display screen, incorporated with buttons, allows inputting the desired number of bags to be stacked together. (up to max.50 bags)
