A system is disclosed for making a layer of soft adhesive. The system comprises an applicator containing a soft adhesive, a gravure cylinder to meter the soft adhesive from the applicator, and a carrier web passing through the gravure cylinder, the carrier web supporting the metered soft adhesive deposited by the gravure cylinder. In exemplary implementations, a dryer may be included for curing the metered soft adhesive on the carrier web.

Abstract: The present invention relates to a draw tape bag having a draw tape made of a polymeric blend of first and second polymeric components having varying densities. The polymeric blend is formed into a film by a blown process known in the art. The film is oriented providing strength and reduced elongation allowing the draw tape bag to be held without sagging or failure under load during usage. The polymeric blend imparts to the draw tape material a sealability and tensile strength that is not achievable by the multi-layer films or single layer films used in the prior art.

Abstract: A rigid, low expansion formable housing composition can be used to package optical waveguide couplers. The housing is in intimate contact with and strongly bonded to the coupler being packaged. The housing composition includes a formable polymeric resin, a glass-ceramic or ceramic or glass filler, and, optionally, strengthening fibers. The filler has a low thermal expansion to compensate for the high expansion of the resin. A moisture barrier layer may be placed around the housing composition, and it is possible to incorporate a shock absorbing material between the housing and the moisture barrier layer.

Abstract: A method and apparatus for the rapid on-line coating of optical fibers with two-package polymer coating systems utilizing conventional liquid fiber coaters is described. The A and B parts of the two-package coating system are continuously combined and mixed together to form a polymerizable coating liquid as the fiber is drawn. This polymerizable coating liquid is continuously delivered to the liquid coater at a rate corresponding to the rate at which it is applied to the fiber, suitable control of the delivery rate being achieved via the use of a feedback signal to the coating liquid delivery system from, e.g., the fiber coater.
