Abstract: The invention relates to ultrasonic welding of industrial fabrics. Specifically, the invention relates to methods for ultrasonically welding the seam area of industrial fabrics using a textured horn and/or anvil. The fabric edges are overlapped as woven or one or both edges can have some warp or weft yarns raveled out. The method involves ultrasonically bonding the overlapped fabric edges, reducing the caliper of the two stacked edges to match the body caliper of the fabric itself. The bonded area can then be perforated using laser or other mechanical means to produce a seam having the same woven texture and permeability (air and/or water) as the body of the fabric.

Abstract: An insulation material having insulative properties of a synthetic down, while have a fir-tree structure more similar to natural down, and being in a blown form. The blowable insulation material is composed of plural units each having a number of filaments that are fused at one end of the unit and are open at an opposite end.

Abstract: A papermaker's fabric and a method of forming a papermaker's fabric, for installation in a papermaking machine. The papermaker's fabric having a plurality of cross-machine, a plurality of machine directional yarns, and a plurality of heat shrunk joints connecting ends of either the machine directional yarns or the cross machine directional yarns to form and continuous loop of fabric. The papermaker's fabric is formed by providing a fixture for securing a plurality of heat shrink tubing sections. Two or more corresponding yarns of the papermaker's fabric are inserted into each of the heat shrink tubing sections and heat is applied to the heat shrink tubing. Upon application of the heat the heat shrink tubing reduces its size to form a tight joint between two yarns inserted therein.

Abstract: A blowable insulation material comprising batt shredded into blowable clusters. In preferred embodiments, the clusters comprise water-repellant or lubricant-finished fiber and/or dry fiber and/or binder fiber and may be mixed with opened fiber. A process to produce the blowable clusters is also disclosed.
