Abstract: A moving web is folded at its predetermined length at its opposite side portions so that the opposite side portions are opposed to each other at a predetermined angle with its central portion. Then part of each of the opposite folded portions is outwardly folded. These foldings occur so that a first folding line and a second folding line being opposed to each other at each side of the web include portions in non-parallel relationship. Elastic bands are affixed onto the web along the second opposite folded portions longitudinally and substantially in parallel to each other. When the web is flattened from the folded condition, the paired elastic band affixed onto the web at its opposite sides each has a diagonal orientation symmetrically with respect to the direction in which the web moves.

Abstract: An elastic ribbon is fed over a vacuum drum. Rotating cutter blades use the drum as an anvil to cut the ribbon into spaced apart segments. A sheet comprising a diaper web runs over a roll that is spaced from the drum. A segment transferring and stretching device is arranged between the drum and roll. One embodiment of the transferring device has grippers rotating together about the axes that are not coaxial but are at opposite acute angles relative to the roll and drum axes. The grippers engage an unstretched elastic segment on the drum when the grippers are close together but as they rotate they spread apart and stretch the segment which is then pressed onto the glue treated sheet. In another embodiment of the elastic segment stretching and transferring device, grippers are mounted to the periphery of a vacuum drum. At least one of the grippers is moved alternately toward and away from the other under the influence of a stationary cam as the drum rotates.

Abstract: Apparatus for producing a continuous sequence of disposable headdresses in which the edge of the cap fabric has been folded inward around a peripherally extending elastic cord to provide a smooth edge which contacts the wearer, and provides superior adhesion between the elastic cord and the cap fabric by utilizing an elastic cord and fabric which are coated with or made of thermoplastically compatible materials. The elastic cord and fabric are assembled by passing the fabric and the cord through a guide system which turns the fabric side edges down from a horizontal plane to a vertical plane while an edge guide lays the elastic cord under the fabric, and then turns the fabric under the cord to sandwich in the folded edge. Warm air preheaters heat the elastic cord and the fabric before completing the fabric fold around the cord. The folded edges with the cord inside pass between dual heat wheels which physically press the fabric to the cord and also seal the fabric edge to the inside of the crown.

Abstract: A band or strap of thermoplastic material which has been placed around a package or article being wrapped is put under tension by means of a tensioning device. The connection apparatus for connecting overlapping ends of the thermoplastic band material is placed within the area of the band or strap under tension and is used to connect these overlapping ends together. The connection apparatus welds the overlapping ends of the strap together using friction by rubbing the lowermost end in a transverse direction with repsect to the longitudinal axis of the band or strap against the uppermost strap end by means of a vibrating or oscillating welding jaw. The welding jaw is driven by an internal battery-powered DC-motor. The connection apparatus is especially well suited for use with a separate tensioning device and can be used in lieu of previously used seal clamps or pliers, independent from a connection with an electric power network or a source of compressed air.

Abstract: A web (102) of backing material to which a web (104) of composite material is adhered is tensioned between two reels (12). A mold (100) is brought into position relative to the webs (102, 104) and located in an oriented closely spaced position relative to a ply (106) cut from the web (104). Localized downward forces are applied to the backing material (102) opposite the ply (106) by extending vacuum cups (40) or ejecting streams of air from nozzles (72). The downward forces move the ply (106) toward the mold (100) and into contact with portions of the mold (100). The ply (106) adheres to the portions of the mold (100) which it contacts. The vacuum cups (40) are moved along the web (102) and then retracted. The suction of the vacuum cups (40) and the tensioning of the web (102) cause separation of the web (102) from the adhered ply (106). When streams of air provide the downward force, the tensioning of the web (102) causes the separation.

Abstract: A system for applying folded outserts to conveyed products utilizing a pressure sensitive tape for transportation from the magazine type hopper to the products. The tape with a pressure sensitive adhesive is routed in front of the outfeed of the outsert hopper. A reciprocating tape tamping device and vacuum manifold mounted on an air cylinder are used to first bump the adhesive-coated tape in contact with the outsert and then withdraw the outsert from the hopper. The withdrawal occurs after the initial precise placement of the outsert to the tape. The method of withdrawal requires further forward movement of a pair of bellow style cups which contact the outsert after adhesion. The initiation of vacuum on contact and termination on withdrawal permit the outsert to be retained individually on the tape. The outsert is then indexed forward where it is transferred to a conveyed product.

Abstract: A rotary film sealing and severing device for use with thermoplastic film for forming packages. The device includes a rotating anvil assembly and a counter-rotating film cutting assembly having a heated sealing and cutting knife. First and second liquid cooled clamping bars on either side of the knife hold the layers of film together while the film is being sealed and cut. Cooling the clamping bars prevents the film from adhering to the clamps and causes the layers of film to quickly fuse together and allows high speed operation by preventing separation of layers of film due to slow cooling.

Abstract: An apparatus and method for coating an elongated pipe wherein a web is coated with a liquid coating composition in a stationary trough and wound spirally around the pipe by turning the pipe over the trough. While the pipe is turned, a web dispenser moves substantially parallel to the rotational axis of the pipe and the dispensed web passes around an elongated bar positioned within the trough to cause the web to be pulled through and coated with the liquid. Movement of the web dispensing means relative to the trough causes the coated web to travel along the bar in a direction transverse to the direction in which the web is dispensed. The web also may travel along a friction member extending substantially parallel to the rotational axis of the pipe so as to tension the web before it is coated.
