Molded fabric and methods of manufacture

Номер: US20120052282A1
Автор: John E. Meschter
Принадлежит: Individual

A novel molded fabric is made by bringing a first patterned group of numerous discrete disjoint elements positioned on a first side of a contact boundary extending throughout the thickness of the fabric being molded, together with a second patterned group of numerous discrete disjoint elements, over-lapping the first group of discrete disjoint elements, on the opposite side of the contact boundary, and joining the elements together at their tip portions. Various techniques are disclosed for maintaining separation of overlapping cross-over portions of the thread elements crossing each other during joining the terminal portions together, so that they simulate woven cloth. First and second rolls can carry the elements in molten form within cavities in the roller surfaces or patterns of solid elements within first and second matrices, can be joined together at the nip of the rolls by heat or chemical means to produce substantial savings in fabric manufacture.

Forming laminated touch fasteners

Номер: US20130280474A1
Автор: Isaac Soler Medina, James T. Grady
Принадлежит: Velcro Industries BV

A laminated touch fastener is made in a continuous process on a mold roll. Flowable resin is pressed against the mold roll in limited areas to form projections extending from resin layers that are laminated to a flexible substrate while carried on the mold roll. In one example a continuous channel about the mold roll is positioned such that the resin at least partially fills the channel as the layers are formed, thereby forming in the channel a raised portion in which the resin layer is of a greater thickness than at a point between the projections and the raised portion. In another example, grooves in the mold roll receive ribs of a pressure applicator during forming of the layers, the ribs blocking lateral flow of the resin to form a desired edge profile.

A headset can include a cable structure connecting non-cable components such as jacks and headphones. The cable structure can be constructed using a molding process. Different approaches can be used to ensure that a conductor bundle extending through the cable structure remains centered within the cable structure during the molding process. A movable tube can be placed in the mold such that the conductor bundle is retained within the tube. As material is injected into the mold and reaches the tube, the tube can be displaced and progressively removed from the mold. Alternatively, the movable tube can be constructed such that the tube may combine with injected material to form a shell of the cable structure. Gates from which material is provided in the mold can be positioned and controlled to facilitate the injection of material in the mold while maintaining the centered position of the conductor bundle.
