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.

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 method of installing flooring and resulting structure are disclosed. The method is particularly useful for sanitary nonslip (or slip resistant) applications such as kitchens. The method includes the steps of positioning a first sheet of polymer flooring material with an upwardly-facing step cut along one edge of the first sheet on a floor to be covered, and applying a second sheet of polymer flooring material with a complementary downwardly-facing step cut along one edge of the second sheet to the upwardly facing step cut of the first sheet and to the floor adjacent the first sheet while concurrently sealing or bonding the respective faces to one another in a step lap joint.

A method of forming a stitchless, adhesively bonded seam for a garment includes positioning an outside surface of a first sheet of fabric adjacent to an outside surface of a second sheet of fabric, and positioning a first strip of adhesive tape between the first and second sheets of fabric. A second strip of adhesive tape is positioned such that a first side is adjacent to a first portion of an inside surface of the second sheet of fabric, and the second sheet of fabric is folded such that a second portion of the inside surface of the second sheet of fabric overlaps a second side of the second strip of adhesive tape. The adhesively bonded seam is formed by applying energy to the first and second sheets of fabric and to the first and second strips of adhesive tape.

The ends of material webs or tapes are joined to each other in an apparatus in which two holding and press-on heads are tiltable about fixed journal axes away from two fixed guide rollers for the webs so that a slide carriage for the heads and for the fixed guide rollers is avoided. The holding and press-on heads are mounted outside of the spacing between the guide rollers, but close to these guide rollers, but with a defined spacing from these guide rollers.

A splicing device to join a first web material coming from a reel being fed (BA), to a second web material (NB), coming from a reel standing by (BB), comprising two heads (107A, 127A; 107B, 127B), each of which comprises: a roller (129A; 129B) associated with a clamping bar (143A, 145A; 143B, 145B) to hold an initial edge of the second web material (NB); a counter-pressure member (109A; 109B) cooperating with said roller (129A; 129B) to press said first and second web material (NA, NB) against each other; a cutting member (111A; 111B); a moving unit (113A; 113B), on which said counter-pressure member (109A; 109B) and said cutting member (111A; 111B) are carried. A first common control member (121) is provided to cause, by the movement it imparts to the moving unit of one or other head alternately: pinching of the first and second web material between the roller (129A; 129B) and the counter-pressure member (109A; 109B); cutting of the first web material; and release of the second web 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.

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.

A gas-sensitive field-effect transistor may be formed from a substrate with a gas-sensitive layer and a transistor processed separately and then assembled. The substrate may be patterned to form spacers by which the height of an air gap between the transistor and the sensitive layer may be adjustable to a relatively precise degree. Formation of the spacers can be achieved by patterning the substrate using material-removal techniques. The height of the spacers may be adjusted in the layer thickness of the gas-sensitive layer and for the transistor fabricated using a CMOS process. Suitable techniques for producing recesses between the spacers include, for example, polishing, cutting, sandblasting, lithographic dry etching, or wet-chemical etching. Suitable materials for the substrate may include, for example, glass, ceramic, aluminum oxide, silicon, or a dimensionally stable polymer. Following preparation of the substrate and the transistor, the two elements of the transistor are joined, for example, using flip-chip methods or adhesive-bonding technology.

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 method and apparatus for thermally attaching web-based polishing pads in a chemical-mechanical planarization (CMP) system. Specifically, one end of a first web-based polishing pad and an end of a second web-based polishing pad are inserted in a thermal sealing unit. The ends of the polishing pads are brought into contact with each other and secured in place within the thermal sealing unit. 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.
