Abstract: Linerless label stock is produced from a single substrate utilizing a coating machine by moving the substrate through the coating machine and applying a tie coating to the substrate first face, a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating. The tie coating comprises a dispersion of a pigment, such as silica, with a binder, such as polyvinyl alcohol. The substrate is cut to form individual labels, and is rolled up into a roll with the release coated second face on the outside of the roll. Printing may be applied to the substrate prior to coating, or to the release coating.

Abstract: Forming a green multi-layer component with an embedded pattern of barrier material, which may be in the form of a positive pattern to form a recessed area or in the form of a negative pattern to form raised areas on the component. Peripheral channels are machined into the green laminate surface to outline each negative or positive pattern feature, the channels being cut deep and wide enough to contact and overlap the edges of the barrier material. The layer of barrier material and the overlying layer(s) of ceramic material are separated from the remainder of the component to produce a non-planar part having raised areas in the case of a negative pattern of barrier material or a part having recessed areas in the case of a positive pattern of barrier material. An apparatus and process to control the machining depth of cut using both AC and DC sensing techniques is disclosed.

Abstract: A drip irrigation hose of the continuous emitter type in which the outlets from the regulating passage each comprise a single longitudinal slit. By controlling the length of the slits and the flexibility of the film, water drips from the outlets when the hose is pressurized without clogging when the hose is depressurized. The slits are sufficiently long and the film is sufficiently flexible so the water drips from the outlets when the hose is pressurized. The slits are sufficiently short and the film is sufficiently rigid so the outlets close completely when the hose is depressurized. An outlet forming wheel has a knife blade on its periphery. A backing wheel engages the outlet forming wheel to establish a first nip therebetween. The backing wheel has on its periphery a circumferential slot into which the knife blade fits at the first nip. A rib forming wheel has around its periphery impressions that define a desired track pattern for the ribs.

Abstract: In a method and apparatus for manufacturing a slide fastener chain having rows of coupling elements and members of a separable bottom end stop assembly, two positioning holes are formed at predetermined positions on reinforcing films attached to a pair of fastener tapes. The positioning holes are used to position the fastener tapes relative to a molding unit with respect to each individual slide fastener length. Thus, even when a positioning error is produced due to a change in tension on the fastener tapes being processed, such error is limited to a small extent which is created only in the individual slide fastener length. Thus, the coupling elements and the first pin member and the second pin member can be molded precisely.

Abstract: Linerless labels are constructed in such a way that when they are manually dispensed they do not tear, but rather rip (separate cleanly) along predefined perforation lines. This is accomplished by providing those cuts of the perforation lines that intersect the slits or side edges of a composite web of linerless labels (and thus the side edges of individual labels when dispensed) have a length great enough to facilitate the start or end of ripping action. The length of each of these end-edge/slit intersecting cuts is at least twice (preferably at least four times) as great as the normal cuts of the alternating cuts and ties forming a perforation line, typically having a length of between about 0.125-0.25 inches (and spaced from each other between about 0.5-1.0 inches), when each of the standard cuts has a length of about 0.012-0.018 inches.

A backing wheel engages the outlet forming wheel to establish a first nip therebetween. The backing wheel has on its periphery a circumferential slot into which the knife blade fits at the first nip. A rib forming wheel has around its periphery impressions that define a desired track pattern for the ribs.

Abstract: Laser perforation of all types of paper provides paper having sufficient strength characteristics to survive stresses imposed during handling, such as experienced in sheet feed processes. The paper so perforated is readily separable along the perforation line when separation is desired. Carbonless paper products particularly benefit from use of a laser in perforation. The paper, capsule, and capsule fill material are vaporized during the laser process, thus forming clean holes and leaving little residual material on the paper.

Abstract: A "green" sheet manufacturing method and apparatus contemplates perforating the "green" sheet with through-holes as it is calendared, rolled or extruded by rollers. To this end, the rollers are each machined with punches of a length one-half the thickness of the "green" sheet and that mate with punches on the other. Any flash or diaphragm obtaining in the through-holes are removed by subsequently exposing the "green" sheet to new mechanisms providing fluid pressure or vibration, or spiking. The bosses or punches may be supplemented with enlargements and other bosses providing for pads and counterholes and grooves in the "green" sheet. The through-holes may be shaped to have a smaller diameter interiorly than at the outer edges to lock in place solder or other conductive media squeegeed into them. The locking action may be enhanced by slightly off-setting bosses or mating punches to produce through-holes whose top and bottom halves are slightly off-set.

Abstract: A tape carrier for electronic components is provided with enlarged regions along cut out lines defining the boundaries of the electronic component mount area. Provision is made for temporarily maintaining the cut out mount area substantially coplanar with remaining portions of the tape carrier. In the preferred embodiment, this is accomplished by way of an adhesive tape bridging the enlarged openings or by tabs or micro connectors bridging the enlarged openings. Thereafter, the mounts can be totally removed from the carrier film by severing the tape or the tabs. The enlarged regions facilitate the severance of the tape or tabs in an automated assembly line environment.

Abstract: A vibration damper is formed from two metal layers. The first metal layer is coated with primer layers, slit, and partially stamped to form a strip holding a plurality of vibration damper blanks. Each of these blanks has a body portion and tab portions. A second metal layer is formed separately by coating a second metal strip with adhesive and stamping it to form a plurality of vibration damper blanks but without tabs. The two strips are aligned, bonded together and the vibration dampers are formed and stamped out. (The tabs, which are only on one layer, are bent to form clips.) Due to this construction the clips cannot delaminate and provide a noiseless metal contact with the shoe plate, while an improved adhesive can be employed to bond the two metal layers together.

Abstract: A method of winding a continuous web on a succession of cores comprises the steps of sequentially rotating a core to which the web is attached to longitudinally advance the web and wind it on the core while applying a strip of adhesive to a transfer roller and then stopping rotation of the core. Subsequently a crosswise row of perforations is formed in the web offset from the core and then the web is longitudinally advanced while pressing the roller against the web to transfer the adhesive strip to the web at and immediately upstream and downstream from the perforation row. The web is subsequently differentially. longitudinally advanced web upstream and downstream of the perforation row to tear the web longitudinally apart at the perforation row, thereby forming a trailing web end attached to the web wound on the core and a leading web end each carrying some of the adhesive strip.
