Polymeric multilayer optical films, and laminate bodies that include such films, are cut or subdivided into one or more discrete pieces by removably applying a first and second liner to opposed major surfaces of the multilayer optical film. Laser radiation is then directed at the multilayer optical film through the first liner in such a way as to produce cut lines that define a plurality of pieces of the first liner and of the multilayer optical film. Thereafter, the plurality of pieces of the first liner are removed from the plurality of pieces of the multilayer optical film while the pieces of multilayer optical film are supported by the second liner. Application of the first liner to the multilayer optical film can be accomplished with electrostatics.

Methods of manufacturing composite webs including a substrate with one or more reinforcing discrete polymeric regions located on or within the composite web are disclosed. Molten nonelastomeric thermoplastic material of the discrete polymeric region is forced against the substrate by a transfer roll. If the substrate is porous, fibrous, etc., a portion of the nonelastomeric thermoplastic composition may infiltrate the substrate and / or encapsulate fibers of the substrate.

A tail end of a web is attached to a winding core via a two-component mechanism having a core component attached to the core and a web component attached to the web, the two components being attached to each other in releasable fashion. The mechanism assists startup of winding. Upon completion of unwinding, the web component detaches from the core component to expose a region of adhesive on a part of the web component that extends from the tail end of the web. The tail end thus can be spliced to a leading end of another web by attaching the leading end to the exposed adhesive on the web component.

A splicing device is disclosed for splicing a first material to a second material in order to continuously feed the materials into a processing line. The apparatus includes a first roll letoff for unwinding a material into a processing line and a second roll letoff for holding a new material that is to replace the first material.

Plastic tubes are welded by first placing the plastic tubes across aligned tube slots in a pair of side by side tube holders. The tubes are clamped to create a fluid free area. The clamps in one of the tube holders are shifted laterally away from the other tube holders to increase the fluid free area of each tube. A cold cutting device cuts through the clamped tubes to create four stub ends. The four stub ends are heated / melted. The stub ends are realigned so that the one stub end in one holder is aligned with the other stub end of the other tube holder and the realigned stub ends are pressed into contact with each other to create a weld seam.

A machine and method for welding first and second fabric panels together. The machine includes a welding head which travels along a frame, applying heat and pressure to an overlapped region of the panels. An infrared camera is positioned to monitor the seam temperature after formation. The camera takes a thermal image across the width of the seam and transmits the data to a central processing unit (CPU). Programming in the CPU compares the thermal image data with a pre-programmed ideal temperature profile. Based on the comparison, the CPU makes adjustments to one or more of the speed of travel of the welding head, and the heat and pressure applied by the welding head, if necessary. The CPU activates an alarm to alert the machine operator if the adjustments aren't successful. The machine further includes a marking assembly for identifying regions on the welded seam which may require post-production testing.

The invention relates to ultrasonic gap welding of flat woven fabrics. Specifically, the invention relates to a method of ultrasonic welding the seam termination yarn ends of a fabric using a controlled gap. A mechanical stop may be employed to control the distance or gap between the horn and anvil to a predetermined level based on the depth of welding and amount of weld energy. By adding another degree of control, the ultrasonic gap welding technique of the present invention is able to achieve fabric seams that are stronger than conventional seams, and even those enhanced with gluing, and is conducive to formation of fabric seams by spot welding or along the termination yarn ends of the fabric.

The present invention provides a method of forming a stitchless, adhesively bonded seam for a garment. The method includes providing a first and second sheet of fabric with each sheet having an outside or facing surface, an inside or backing surface, and an edge. The outside surface and edge of the first sheet of fabric are positioned adjacent to the outside surface and edge of the second sheet of fabric, respectively. A first strip of adhesive tape, having first and second sides and an edge, is positioned between the first and second sheets of fabric such that the edge of the first strip of adhesive tape is adjacent to the edges of the first and second sheets of fabric, and the first and second sides of the first strip of adhesive tape are adjacent to the outside surfaces of the first and second sheets of fabric, respectively. A second strip of adhesive tape, having first and second sides and an edge, is positioned such that its edge and first side are adjacent to the edge of the second sheet of fabric and to a first portion of the inside surface of the second sheet of fabric, respectively. The second sheet of fabric is folded such that a second portion of the inside surface of the second sheet of fabric overlaps the second side of the second strip of adhesive tape. The adhesively bonded seam is formed by applying ultrasonic sound pressure to the first and second sheets of fabric and to the first and second strips of adhesive tape, causing the first strip of adhesive tape to join the outside surfaces of the first and second sheets of fabric and the second strip of adhesive tape to join the first and second portions of the inside surface of the second sheet of fabric.

A heating element within thermal sealing unit is activated, thereby fusing the polishing pads.

A tape splicing mechanism joins the tail of one tape to the leading edge of another tape. A frame defines a passageway along which the tape passes. A pair of arms rotatably attached to the frame have projecting posts and rotate between a first position where the posts are closer to the pathway and a second position where they are further from the pathway. The arms are urged toward the first position and a catch mechanism holds them in the second position until released by a release mechanism when a release indicia in the first tape passes. The leading edge of the second tape is looped around the first tape to form a loose knot and is tied to the post on each side of the first tape. When the arms are released they move to the second position and tighten the knot.
