  • Patent number: 11766844
    Abstract: Methods and structures are provided for a dunnage system to facilitate efficient coupling together of supply units of pre-configured sheet stock material, such as, for example, separate units of fanfold stacks of pre-configured sheet stock material, in a manner of continuous supply with a continuous pocket extending longitudinally between the separate supply units, so that they can interact with an expander of the dunnage system without disruption as one supply unit is depleted and a next supply unit is fed through the dunnage system. Also, various methods, apparatus, and systems are provided to facilitate smooth operation of a dunnage machine of the dunnage system to reduce a tendency of the pre-configured sheet stock material to jam and to increase the tendency of dunnage product generated to reflect a desired shape and stability.

  • Patent number: 11541621
    Abstract: A machine for converting a sheet material into a relatively less dense dunnage product includes a forming assembly and a feeding assembly downstream of the forming assembly. The forming assembly is configured to cause lateral edges of the sheet material to roll towards one another, forming a tubular shape. A deflector at a downstream end of the forming assembly is configured to engage the lateral edges of the sheet material and to urge the lateral edges into an interior of the tubular shape. This juxtaposes lateral edge portions of the sheet material adjacent the respective lateral edges. A forming channel at a downstream end of the forming assembly faces the deflector to receive the lateral edge portions and shape them into a tab. Finally, the feeding assembly includes rotating connecting members that engage and connect together the overlapping lateral edge portions of the sheet material forming the tab.

  • Patent number: 9533809
    Abstract: A slit web material has a curvilinear structure that is substantially longer than it is wide, with specially shaped slits, “tilde-slits”, which permit relatively easy expansion upon deployment. The cuts are arranged in continuous rows of tilde-slits. In any given row, the tilde-slits follow one-after-the-other in a curvilinear direction. Adjacent rows of slits are parallel to each other, but are offset from one another such that a line drawn between adjacent tilde-slits in adjacent rows is not perpendicular to the direction of the rows. The invention contemplates that the material dispenses from a continuous roll. If the slits are arranged in the longitudinal direction, then the web material expands in the width direction only upon deployment. However, if the slits are arranged such that the row direction is at some angle to the longitudinal direction, then the web material expands in both directions upon deployment.

  • Patent number: 4590715
    Abstract: A tarpaulin or other similar protective cover of flexible sheet material is adapted to be tied down securely with the aid of a single tie-down line extending around its periphery. The periphery is edge-finished with a continuous hollow conduit laterally fluted at equally spaced intervals with identical semi-circular cut-outs deep into the hollow conduit. Each cut-out defines a hole in the conduit wall which, in use of the tarpaulin with a tie-down line loosely contained in, and longer than, the conduit, permits a length portion of the line to be pulled outwardly from the conduit in a looped configuration for anchoring attachment to a respective tie-down device. Tearing of the tarpaulin by anchoring forces exerted thereon by way of the single tie-down line is effectively resisted, notwithstanding the absence of grommets or other relatively expensive reinforcement measures.

  • Patent number: 4532168
    Abstract: A heat shrinkable covering in the form of a sheet which is heat shrinkable in a longitudinal direction, and a stiffening member connected at each of two longitudinally spaced transversely extending superimposable zones of the sheet. One stiffening member has holes and the other studs in the form of arm portions which are insertable through the holes to secure the stiffening members together. The arm portions can be flattened down onto the outside of the covering to retain the stiffening members together while reducing risk of the studs interfering with items such as cables adjacent the covered article. Preferably the studs have a resiliently compressible head portion which snap fits into holes formed through the sheet adjacent the holes in the stiffening member to facilitate locating the overlapped zones of the sheet relative to one another. In use, the sheet is wrapped around an article, the stiffening members are engaged together, and the sheet is then heat shrunk.

  • Patent number: 4507011
    Abstract: A reinforced elastomer attachment joint includes an elastomer section (304) butt bonded to a FIBERGLAS section (332), a boundary line (340) being defined therebetween. One or more fabric plies (338) are embedded within the elastomer (304) and FIBERGLAS (332) sections so as to be capable of transmitting loads from the elastomer section (304) to the FIBERGLAS section (332). The rigid FIBERGLAS section (332) is capable of being drilled and countersunk so as to accomodate fastening means (306) whereby the attachment joint can be secured to basic support structure (302).

  • Patent number: 4482413
    Abstract: A strip (56) of non-metallic material and one (59) of a metallic material are wrapped simultaneously about an advancing cable core (32) to enclose partially the core. Then longitudinal edge portions (71, 72) of the strip of non-metallic material are separated by a shoe (150) which permits movement of the edge portions in a direction circumferentially of the core. One longitudinal edge portion (72) of the non-metallic strip becomes confined in a guideway (118) of a tool (99) and longitudinal edge portions (73, 74) of the metallic strip (59) are guided along guideways (117, 118) of the tool as the strips are moved through a converging passageway (103). This controls the relative circumferential movement between the edge portions as the strips are moved through the passageway to form a core wrap (33) and a shield (34).

  • Patent number: 4442153
    Abstract: A longitudinally divided cable sleeve having a strip-like sleeve member composed of thermo-plastic synthetic material having a memory shape characterized by the slot between the edges being covered by either the longitudinal edges being overlapped with respect to one another or one of the edges having an overlapping extension and with at least one of said edges having a mechanical reinforcement so that the edges are more thermally stable than the remainder of the strip when subjected to heat for shrinking the sleeve onto an object. The reinforcements may be completely embedded into the material of the strip, partially embedded or placed on outer surfaces thereof. Preferably, the reinforcements also support or provide interlocking connecting elements such as hook and catch elements for securing the edges together and the connection elements aid in taking up the shrinking force created during the shrinking operation.

  • Patent number: 4287011
    Abstract: A method of making a bond structure and a bond structure are provided that produce concurrently a peel bond and a lap bond. One end of a sheet to be joined to a second end of the same or other sheet is folded back on itself and on end of the other member inserted. The two pairs of contacting surfaces thus formed are subsequently bonded to each other. The bonding may be by any means and the clamping force across the bond during bonding need be applied from one side of the sheet only. By insuring that the peel bond fails before the material, a flat lap bond may be achieved by causing only the peel bond to fail.

  • Patent number: 4259131
    Abstract: Straps or belt loop strips are formed with the apparatus and method of the present invention by folding a strip of fabric about a strip of fusible material, threading the folded, combined strip back and forth between two side-by-side, counter-rotating cylinders so that, in the preferred embodiment, the strip forms a plurality of figure eight patterns over and between the two cylinders, and heating the cylinders to a temperature which is above the melting point of the fusible strip but below the scorching point of the material. The speed at which the cylinders are counter-rotated with respect to each other is chosen, in conjunction with the number of loops of the combined strip over the cylinders, to place the combined strip in contact with the heated surface for a length of time sufficient to accomplish complete fusing.
