Abstract: The present invention is a method for seaming a polyimide material. The method involves forming an interface between multiple the polyimide materials. Next, heat is applied to the interface to soften the polyimide material. The temperature of the heat source is below the melting point of the polyimide material. Finally, pressure is applied to the interface to create a seam between the polyimide materials.

Abstract: An insert feeding assembly includes an insert support, an overlapping feeding assembly, a separating assembly, and a main drive assembly. The insert support provides support for a stack of inserts, the overlapping feeding assembly converts the stack of inserts into an overlapping stream of inserts, and the separating assembly separates individual inserts from the overlapping stream and ejects these separated inserts out of the feeding assembly. The insert support includes an insert plate assembly and an insert guide assembly. The overlapping feeding assembly includes a suction cup assembly, a lap roller drive assembly, and a belt conveyor assembly. The separating mechanism includes a speed up roller assembly. The feeding assembly includes approximately 50% fewer parts than other known feeders and can operate at a printer press speed of approximately 75,000 inserts per hour.
