Abstract: An automatic lacer wraps bundles of polymeric fibers with thread, before the bundles are woven into a fabric mat and placed in a housing to form a gas-separation membrane module. A fiber bundle passes through a spool which is previously wound with thread on its outer surface. The thread is attached to the fiber bundle, so that when the bundle is moved through the spool, the thread is pulled from the spool, and automatically becomes wound around the bundle. Threads from two or more spools may be wrapped around the fiber bundle simultaneously. Lacing of the fiber bundles reduces the amount of tangling in the loom feeder, and improves the quality of modules made from the fiber bundles.

Abstract: An animal chew including a plurality of fibers which are wound together to form rope strands. Two or more rope strands are twisted together to form a rope segment. A ribbon baring indicia is either interlaced with the rope segments or helically twisted around the perimeter of the rope segment. The indicia printed on the ribbon can either be of a fun nature, a commercial nature, or a public safety nature.

Abstract: An expandable chain construction comprises first and second chain lengths of a monofilament such as nylon fishing line. Each chain length is formed into a series of spaced loops, the loops of the two lengths being of opposite senses. Each loop of each length encircles a portion of the other length lying between a pair of loops. Chain constructions may be interconnected along their lengths to form chains of increased width. The chain constructions are expandable to fit closely but gently about a wearers limb. The construction can simulate the appearance of tatoo designs.
