ABSTRACT:
A method and apparatus for joining crinoline to drapery material to provide a stiffening for pleats.
The method consists of laying the drapery material face down on a table where it is secured by clamping devices at opposite ends so as to maintain the material in a stationary position.
The joining apparatus is activated to move across the edge of the drapery material which is to undergo the crinoline-bonding step. A feed roll dispenses a crinoline strip and, simultaneously, a second feed roll dispenses an adhesive filament which is interfed between the said crinoline and said drapery material. A preheater directs warm air over the crinoline immediately prior to its emplacement upon the material, whereupon, a heat wheel follows to apply heat and pressure to the combined layers of material, tape and crinoline so as to liquify the adhesive and cause it to spread so that it joins the crinoline and the material in a permanent bond.
Also, in addition to preheating the crinoline, the material is preheated to afford a more rapid and effective seal.
A cutter and cutter guide follow the heat wheel in a slotted track whereupon the excess of joined material and crinoline are cut off to provide a proper finish.
