Claims16
A system comprising:
- a conveyor;
- a separator;
- a controller operatively connected to the conveyor and to the separator to control the conveyor to drive a custom length of a flattened tube of stock packaging material through the separator, and to control the separator to separate the custom length of the tube from the tube to form a pouch pre-from;
- and
- a first closer assembly operatively connected to the separator to receive the pouch pre-form, wherein the first closer assembly includes:
- an adhesive applicator mounted for lateral movement relative to a slide that is configured to apply adhesive to one open end of the pouch pre-form;
- a pressure plate configured to close the one open end of the pouch pre-form after application of the adhesive;
- and
- a set of metal fingers positioned above the pressure plate and the adhesive applicator and in opposition to the slide, wherein the fingers are configured to guide the pouch pre-form into the first closer assembly and assist in forcing the pouch pre-form flat against the slide in case of unwanted upward memory in the pouch pre-form.
