Abstract: A conveyor system includes an elongated vacuum plenum having an interior defined between upwardly and downwardly facing surfaces between opposing ends. A slot defining a portion of a conveyor path is formed in the plenum and extends from one end of the plenum at the upwardly facing surface toward the other end and the downwardly facing surface. A plurality of conveyor modules forming part of an endless loop are received in the slot and move along the conveyor path. At least some of the modules have at least one opening in fluid communication with the interior of the plenum. An object disposed on at least one of the modules is held against the at least one module by a vacuum in the interior of the plenum as the at least one module moves along the conveyor path from the upwardly facing surface toward the downwardly facing surface.

Abstract: An air conveyor system includes a base, a first guide position relative to the base, and a guide adjustment mechanism coupled to the first guide. The guide adjustment mechanism infinitely adjusts the first guide within a predetermined range and includes an electric linear actuator and a pivot arm coupled to the electric linear actuator that rotates in response to adjustment of the electric linear actuator. The guide adjustment mechanism also includes a first linkage arm coupled to the first guide and the pivot arm. The first linkage arm laterally moves the first guide responsive to rotation of the pivot arm.

Abstract: A shrinkable polymer film including a modified polyester resin polymerized from monomers including a dicarboxylic acid and a glycol, wherein the glycol includes 2-methyl-1,3-propanediol, and wherein the polymer film shrinks at least about 50% in a main shrinkage direction after ten seconds in an 80 degree Celsius hot water bath.
