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.
Claims19
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 fabric webs and is connected to the glue system.
A machine for making cellular products of the type in which fabric from a supply of fabric is passed under a glue applicator and wound on a collector wherein the improvement comprises:
- a variable speed motor connected to and driving the collector;
- a sensor adjacent the glue applicator that senses a speed at which the fabric passes under the glue applicator and generates signals corresponding to sensed speeds;
- and
- a controller connected to the sensor and the variable speed motor which directs the variable speed motor to change speeds in response to signals from the sensor.
A machine for making cellular product comprising:
- a supply of fabric;
- a first fabric drive which draws fabric from the supply of fabric;
- a glue applicator which applies at least one glue line to the fabric;
- a second fabric drive which receives fabric to which glue has been applied and the first fabric drive being capable to move the fabric past the glue applicator such that the fabric is not stretched as the fabric passes the glue applicator;
- and
- a collector which receives fabric from the second fabric device and overlaps the fabric to form a cellular product.
