Abstract:
A method that includes the steps of (i) attaching a leading portion of a supply of stock material to a trailing portion of a preceding supply of stock material by means of a mechanical fastener, an electromagnetic field, electrostatic charges, or an activatable bonding agent, and (ii) converting the stock material into a relatively less dense dunnage product. The attaching step may include (a) embossing, punching, stitching, stapling, riveting, clipping, snapping, buttoning, attaching with male and female interlocking devices or hook-and-loop fasteners, (b) integrating one or more elements into the stock material to provide a stock material with magnetic or magnetizable material in the leading or trailing portion, (c) imparting opposing and attractive magnetic charges in respective leading and trailing portions, (d) inducing an electrostatic charge or a magnetic field in at least one of the leading and trailing portions, and/or (e) activating a bonding agent.
Abstract:
An adhesive tape (8) for use with high-speed webs whichprovides for adherence between two surfaces (e.g., 10B, 11A) before allowing the tape to separate along a specific interface (2A) between two non-adhesive layers (2, 3). The separation of tape along the specific interface results in the absence of any exposed adhesive surfaces and provides for improved performance in a variety of uses.
Abstract:
A roll-shaped original cloth web having joints formed by winding, in a roll shape, a web formed by joining the end edges of long webs to each other, wherein a joint index part (M) having a projected part (FM) of irregular shape is formed at a joint (J) or adjacent to the joint (J), whereby the projected part (FM) of the joint index part (M) does not need to add another member for the index part because the projected part is formed integrally with the web, the projected part (FM) can be formed easily by pressurizing from the front and rear of the web, and the joint can be detected easily because the joint index part (M) is formed irregularly.
Abstract:
The method for splicing together first (10) and second (20) webs of pre-creased laminated packaging material for manufacturing sealed packages of pourable food products in a form, fill and seal type packaging machine, includes the steps of holding an end portion (18) of a first web (10), with its inner surface (14) oriented in a predetermined direction. An end portion (28) of a second web (20) is cut to form an undercut surface (29). The undercut surface (29) of the second web (20) is superimposed onto the end portion (18) of the first web (10), with the outer surface (27) of the second web (20) in contact with the inner surface (14) of the first web (10). THe undercut surface (29) of the second web (20) is then bonded to the end portion (18) of said first web (10). At the splice (30), the inner surface (14) of the first web (10) and the inner surface (24) of the second web (20) together define an integral, continuous inner surface (14, 24).
Abstract:
The device is designed to connect a rod-like body (1) to a strip-like edge (11) of a flexible flattish structure (10). The flat structure (10) can be put under tension (15) transversely to the edge. The device comprises a longitudinal groove (2) in the rod-like body and a rod section which can be inserted into the groove (2). In cross section the groove consists of two arms (21, 22) forming a narrow passage (20) at the groove aperture. The rod section, together with the flexible flat structure (10), the edge of which is partially surrounded by the rod section, can be inserted into the groove. There is a curve (30) on the rod section for the flat structure by means of which a tensile force (15) acting on the flat structure transversely to the edge exerts a torque on the rod section. This torque clamps the flat structure between the rod section and the two arms at at least one point (210, 220).
Abstract:
In a device for splicing two thin film web portions (5, 6) comprising a roll supplying a web of film material, a roll for winding a web of film material and a splicing table (2) adapted to be subject to sub-atmospheric pressure and having a first groove (3) therein defining a cutting line and means for applying a splicing tape (9) to unite said first and second webs of film, the splicing table includes a second groove (4) that is parallel to the first groove, both grooves being perpendicular to the longitudinal direction of the webs of film, the vacuum table being thus split into three regions each individually adapted to be put under sub-atmospheric pressure, the device being useful for highly accurate splicing of webs of ultra-thin film material.
Abstract:
The present invention relates to a method for splicing an upstream section and a downstream section of a multi-layered laminated sheet material wherein each section of the material comprises at least three layers each having first and second surfaces and wherein the at least three layers comprise first and second outer layers and at least one inner layer located between the first and second outer layers, comprising the steps of a) splicing together the upstream and downstream sections of both the first and second outer layers with a splicing material; b) removing the first outer layer from the multi-layered laminated sheet material to expose a surface of an inner layer; c) splicing the upstream and downstream sections of the exposed inner layer with a splicing material; and d) applying a replacement first outer layer to the exposed surface of the inner layer. A spliced multi-layered laminated sheet material produced according to the method is also provided. Also provided is an apparatus for splicing two sections of a multi-layered laminated sheet material wherein each section of the material comprises at least three layers each having first and second surfaces and wherein the at least three layers comprise two outer layers and at least one inner layer located between the two outer layers, the apparatus comprising: a first splicer configured to apply a splicing material to the two outer layers of the multi-layered laminated sheet material, a delaminator configured to remove a first outer layer, a second splicer located downstream of the delaminator configured to apply a splicing material to the exposed inner layer and an applicator located downstream of the second splicer configured to reapply an outer layer to the exposed inner layer.
