Abstract
A machine for making collapsible cellular structures folds two fabric webs into a V-shape or C-shape, connects the webs together with strands of adhesive, applies glue lines and collects the webs on a wheel. A variable speed motor, a fabric drive system which enables glue to be applied when the fabric is not stretched and a lay-on wheel assembly with movable arm that directs the fabric onto the collector can be provided in the machine.
Claims12
A machine for making cellular products comprised of:
- a supply containing at least two rolls of fabric web;
- a web folder connected to the supply which receives two fabric webs and folds each web to a V-shaped or a C-shape;
- a strand making assembly connected to the web folder which receives the folded fabric webs and applies strands between the two fabric webs connecting the webs together;
- a glue system connected to the strand making assembly which applies at least one glue line to the fabric webs;
- and
- a collector wheel which receives the interconnected fabric webs as successive turns or wraps of interconnected fabric webs, successive turns or wraps being adhered to former turns or wraps along the at least one glue line.
