Abstract: A continuously operable press for the manufacture of laminates and similar products has a heated press roll, two guide rolls, and at least one tensioning roll. One end of the rolls is journaled in bearings at a fixed support wall and the other end of each roll is removably journaled in bearings of a movable support wall. A pressure belt is passing over the rolls, but a decorating roll sleeve can be slid on and of from the press roll, and this provides a decoration on the adjacent laminate surface. The press has a device for lifting the relaxed pressure belt so as to remove the decorating roll sleeve. The lifter device has at least two transverse lift bars with suction heads, and the lift bars are distributed about the upper circumferential region of the press roll. Compressed air can be introduced between the press roll and the decorating roll sleeve when taking the decorating roll sleeve from the press roll.

Abstract: A hot melt carpet seaming support which includes a plurality of flat generally rectangular slats, wherein the mid portion slats are slidable on a flexible wire or filament into abutting relation forming a flat continuous support for the heat bonding carpet tape beneath the opposed edges of the carpet sections to be joined. The carpet seaming support thus provides a firm support during bonding which avoids heat damage to the carpet pad. Further, the carpet seaming support is flexible about the wire or filament for easy removal of the seaming support particularly at the wall and coiling for storage. The method includes arranging the slats in abutting side-to-side relation beneath the carpet sections to be joined for receipt of the bonding tape and removal of the seaming support following bonding, as defined.

Abstract: The invention is an apparatus for applying a tensioned elastic ribbon or ribbons transversely of a moving web or material. It is particularly well adapted for applying elastic to the waist zones of disposable diapers moving continuously in an end-to-end assembly. The apparatus has a supporting frame with a shaft providing an axis of rotation for at least one rotatable radial arm. A polygonal head is mounted at the end of each arm. This has a number of peripheral edges with clamps or vacuum orifices for holding a tensioned strand or strands of elastic ribbon. A drive rotates the radial arms and a rotating mechanism moves the heads (360/n).degree. for each full rotation of the radial arms where n is equal to the number of peripheral faces on the head. An anvil acts against the head at the time of application of the tensioned elastic to the moving web. The web is passed between the head and the anvil along a path describing a chord or tangent of the circle of rotation of the radial arms.

Abstract: Product and process for heat transfer labeling. A transfer layer containing a design print is superimposed upon a contoured release layer that is desirably imprinted on a carrier. When the carrier, together with the release layer and the transfer layer are applied to an object to be labeled and heated, both the release layer and the transfer layer become molten and the transfer layer becomes adhered to the object being labeled. The release layer and the transfer layer are immiscible when in a molten state. The desired immisciblity can be achieved by the inclusion of a barrier layer between the transfer layer containing the design print and the release layer.

Abstract: A vacuum drum for carrying a label held to its surface by vacuum past an adhesive applying roll to a position where the label will touch a container and the container will be rolled along the drum surface to thereby apply the label about the container. The drum is provided with a circumferential series of vacuum ports that extend through its outer surface. The vacuum to the ports is fed through passages in a bottom support plate for the drum and the passages all communicate with a stationary vacuum chamber in a collector ring which is held against the inner surface of the drum supporting plate. The collector ring vacuum chamber extends about the axis of the ring for about 180.degree. and at one end thereof serves to close off the passages to the drum in radial succession as the label is transferred to the container. Each passage, after being shut off from the vacuum, is vented.

The tongues of the edging strips are stuck to the sheets, and the sheets stuck to one another, by double sided adhesive tapes of appropriate thicknesses. After the two sheets have been stuck together and to said edging strips, cloth or the like covering material is stuck to the outer face of each sheet and surplus edge portions of the cloth or the like are tucked between the edging strips and the adjacent edges of the sheets of rigid material.

Abstract: A method of constructing a collapsible mandrel for use in fabricating filament wound vessels or tanks includes the steps of preparing a rigid mandrel and supporting the mandrel on a rotatable axle, applying one or more layers of strips of rubber longitudinally on the mandrel to form an enclosure, applying coats of rubber solution over the layers, winding a layer of fibers over at least one of the layers, and curing the rubber layers. The layers are cut into two parts, removed from the rigid mandrel, and rejoined by using reinforcing straps along the seam of the joined parts. The collapsible mandrel may be used to fabricate either filament wound tanks or other collapsible mandrels, neither of which would have a seam or joint since, after constructing the tank or second mandrel on the first inflated collapsible mandrel, the first mandrel would be deflated, collapsed and removed from the interior of the tank or second mandrel.
