Abstract
Apparatus for heat treating thermoplastic fabric at the loom is illustrated including an elongated housing extending across the full width of the loom having a passageway therethrough dividing the housing into opposed chambers, one of which carries a heating element and the other, a reflector so that the fabric is heated from both sides, and a gripping means is disclosed for tensioning the fabric in open width as it passes the heater means with a suction device for removing gases and fumes generated by heating of the thermoplastic fabric to elevated temperatures.
Claims2
An apparatus for heat treating fabric at the loom comprising:
- an elongated housing extending across the full width of the fabric;
- a passageway extending through said housing permitting the fabric to pass therethrough in open width and dividing said housing defining a pair of opposed chambers therein;
- a heating element carried by said housing in one chamber;
- a heat reflector carried by said housing in the other chamber opposite said heating element so that the fabric passes between the heating element and the reflector;
- means for restraining the edges of the fabric in open width against shrinkage during the application of heat thereto;
- an air hose communicating with the interior of said housing;
- means developing suction on said air hose;
- whereby fumes developing from the action of heat on the fabric may be withdrawn from said housing.
