Abstract:
A rotating mold roll (215) defines an array of molding cavities (252). The mold roll (215) is positioned adjacent a pressure device (220, 280) to define a pressure nip (235, 285). At least one of the mold roll (215) and the pressure device (220, 280) define a molding recess (250, 257, 253) that is larger than the molding cavities (252). Resin (230) is introduced to the rotating mold roll (215) and pressed into the molding cavities (252) and the molding recess (250, 257, 253) to form discrete projections (130, 530, 630, 830, 930) and a series of discrete, longitudinally spaced apart structural features (110, 510, 610, 710, 810, 1410). The projections (130, 530, 630, 830, 930) and structural features (110, 510, 610, 710, 810, 1410) are carried on a continuous sheet-form base (115, 515, 615, 715, 815, 1415). The resin (230) is removed from the mold roll (215) to expose a continuous preform sheet including the base (115, 515, 615, 715, 815, 1415), the projections (130, 530, 630, 830, 930), and the structural features (110, 510, 610, 710, 810, 1410). The structural features (110, 510, 610, 710, 810, 1410) are arranged along the preform sheet in a longitudinally repeating pattern. The preform sheet is separated into multiple discrete products including an array of the projections (130, 530, 630, 830, 930) and at least one of the structural features (110, 510, 610, 710, 810, 1410).
Abstract:
A fastener element (10, 11, 32, 34, 90, 100, 120, 121, 123, 127, 129, 139, 142, 146, 170, 174, 350, 370) with a sheet-form base (14) and an array of wedge-shaped engageable elements (12) molded integrally with a surface of the sheet-form base. The wedge-shaped elements each have a steep side (18) and a gradually rising side (20), and are arranged with their steep sides all directed in a common sense, such that the array can engage a similar array of oppositely-directed wedge-shaped elements to resist shear motion. The distal edges (17) of the wedges are curved in top view.
Abstract:
A bi-directional locking socket for use with a seal device which includes a shackle having a plurality of locking elements on a surface thereof. The socket comprises a locking insert forming a locking arrangement including a body defining a chamber therein. The locking insert further includes opposing top and bottom ends where the top end defines a top opening communicating with the chamber, and the bottom end defines a bottom opening communicating with the chamber. A plurality of mirror image spaced fingers define a passageway extending through the chamber. The plurality of fingers allow passage of the locking elements as a free end of the shackle is pulled through the passageway via either the top or the bottom openings in opposite insertion directions, and lock with a locking element of the shackle when the shackle movement is in an opposite direction to the insertion direction. In the alternative, the socket has a chamber with the locking arrangement formed one piece therewith.
Abstract:
Strap (2) for bundling a strapping item (4), e.g. bundles of cables, hose connectors, pipes, and other items, where the strap is designed so that it is wound at least twice around the strapping item (4), having the common feature that all forces in connection with the tightening are absorbed in a relatively small area around the strapping head (6), providing a limitation to the force with which such a strap can be tightened. There is indicated a strap (2), the sides (10, 12) of which including mutually interacting toothings (26, 28), and where the strap includes a crossing aperture (16) in a broader section (14) in the extension of which is found a strapping head (6), including an aperture (92) communicating with an open groove (94) at the underside (96) of he strapping head, the groove running between the aperture (92) in the strapping head (6) and the crossing aperture (16). The mutually interacting toothings are hereby guided into mutual engagement, and the force from tensioning the strap is distributed over a large part of the strap which hereby may be tightened with greater force.
Abstract:
A cable tie (11) is used in conjunction with a cable tie installation tool (12) to bundle a plurality of objects, such as wires or cables. The cable tie includes a head (13) and a tail (15), the head (13) having a pair of outwardly projecting wings (31-1, 31-2). The tail (15) is capable of insertion through the head (13) so that the cable tie takes the shape of a loop with the tail (15) engaging and being locked in position by a pawl (26) inside the head (13), the tail (15) being incapable of removal once it is inserted in the head (13). The cable tie (11) installation tool (12) includes a housing (101) which is adapted to receive an individually loaded cable tie and which protects internal components of the tool (12). A jaw assembly (105), which includes a motor driven by a motor (153) into open, closed and overclosed positions, guides the tail (15) through the head (13) to form the cable tie (11) into a closed loop around the desired bundle.
Abstract:
A dual material cable tie includes a tail on a first end, a head on a second end, and an elongated strap extending therebetween. The strap and tail are substantially flat and formed from a first material. The tail can have teeth/ridges on one or both of the surfaces that extend outwardly from the surface(s). The head has a first portion, a second portion and a passage extending from a first end to a second end that receives the tail. A pawl is located in the passage and the second portion includes an exterior surface. The first portion of the head is made from a first material and the second portion is made from a second material that can be stiffer than the first material and the hardness of the second material can be the same or greater than the first material.
Abstract:
A protective catheter tip has a generally tubular body portion defining an interior cavity. The proximal end of a urinary catheter is at least partially received within the protective tip, with the protective tip being retained on the urinary catheter without the need for a sleeve connecting the protective tip and the catheter. The protective tip may include a projection received within a draining hole or eye at the proximal end of the catheter to retain the protective tip on the catheter. The protective tip may instead include one or more projections that apply a frictional force to an outer surface of the catheter to retain the protective tip on the catheter. The protective tip may instead be retained on the catheter by a tether extending between the protective tip and a distal end of the catheter. The protective tip may also be provided in two pieces.
Abstract:
A cable tie comprising a flexible tail portion connected to a head portion comprising at least a pair of substantially rigid side walls, said head portion further comprising a first slot, through which said flexible tail portion may be passed and retained, said first slot being in communication with an opening in an outer wall of said head portion, said opening allowing removal of the flexible tail portion therethrough.
