Abstract
A continuous system applies chemical solutions to successive rolls of fabric from alternate applicators. The treated rolls pass through a plurality of stations within a common development chamber, emerging fully processed in one continuous movement. Radiant heat and steam are applied throughout the chamber and a winding and rewinding operation provides uniform treatment. An inclined chamber section permits gravity feed of the rolls.
Claims14
A system for treating fabric comprising:
- an enclosed chamber having an entrance and an exit and a plurality of stations therebetween;
- fabric supply means for feeding fabric continuously into said chamber;
- applicator means positioned in the path of said fabric for applying solutions to said fabric;
- take-up means at a first station within said chamber adjacent said entrance for winding said fabric into rolls;
- means within said chamber for applying heat and steam to the rolls of fabric;
- means for feeding successive rolls of fabric along said chamber and for holding respective rolls within selective stations for predetermined time intervals;
- a second rest station for permitting further application of heat and steam to said roll;
- a third rewind station including means for rewinding fabric from a first roll onto a second roll and means for subjecting said second roll to additional heat and steam capable of maintaining a predetermined temperature to provide uniform heat and moisture throughout the roll;
- a fourth station including gravity drive means for holding and moving a plurality of rolls successively toward said exit while continuing application of said heat and steam on said rolls;
- and
- means for holding said rolls upon exiting from said chamber.
