摘要:
In order to produce an adhesive binding for bookbinding, in which the sheets, in quarto format, are perforated on the folding edge, folded, provided with adhesive on the folding edge and assembled to form an inner book, the perforating process is carried out on the folding edge in such a manner that two interrupted perforation lines (12, 13) are punched, these perforation lines being parallel at a short distance from one another, offset in a longitudinal direction, and forming a widened folding edge (14). The punch locations of both perforation lines (12, 13) are, along the folding edge (14), offset by the length of one perforating tooth. The quarto format sheets, which are folded on the folding edge (14) and which are assembled and squeezed to form an inner book, are provided with the application of adhesive on surfaces, which are formed by the double perforating and which are assigned to one another, between full locations of one perforation line (12) and full locations of the other perforation line (13).

The invention relates to a shaping method that first comprises preparing a perform (3) by T-punch cutting in a plate or a strip of a cellular foam coil, then transforming said preform (3) so that it takes a shape corresponding to the final part (1), i.e. a polygonal or nearly cylindrical shape, depending on the case. The preform (3) has an outline that fits in a rectangular imprint, and it is cut for forming a slot (6) in the middle longitudinal portion thereof while keeping a portion of material at each end which is sufficient to be used as a hinge (7); it further comprises deep V-shaped notches (8) on its outer outline while also maintaining at said slot (6) a portion of material that is sufficient to be used as a hinge (9).

Some aspects of the present invention are related to a mop and/or mop head that allows larger debris to pass over at least a portion of the mop head and into a receptacle of the mop head. In some embodiments, the mop head and the receptacle are integrally formed. The mop has debris collecting material coupled to the mop head to collect dust, dirt, and other relatively small debris as the mop moves over a floor. In one particular embodiment, the debris collecting material is a non-woven material. The debris collecting material of the mop can be connected to the mop many different ways. However, in some embodiments, the material is connected via several projections extending from a top surface of the mop head. The projections pass through apertures in the dust collecting material.

In an arrangement for machining an elongate object (1), successively arranged tools (5) are in turn pressed against the object and machine the latter during movement of the object in the longitudinal direction, the object being supported by a stay (4). In this connection, the tools (5) are first moved along a rising first ramp (9), to a ridge (11) thereon, after which they start to travel down a falling second ramp (12) and in this connection are pivoted about a pivoting center located at a spacing from the object, so that they are pivoted out of engagement with the machining location. In this connection, a strip-shaped object can be slit and stretched along the strip outside at least one edge of the stay, so that openings are formed in the object in mutually laterally displaced rows along at least one long side thereof. The tools (5) are each arranged on their own chain link (6) forming part of a chain (7).

The invention concerns a method of manufacturing an easy-to-open shrink sleeve wrapped package comprising wrapping up one or more products in a shrink thermoplastic film and submitting the obtained sleeve to a heat shrinking step to give a tight package, wherein the package comprises a tear strip defined by perforations to facilitate opening of the package, said method being characterized in that a) the tear strip is defined by a close sequence of pairs of mutually diverging weakness segments, having the same or substantially the same shape and size, and diverging in the same direction, and b) said sequence of pairs of mutually diverging weakness segments is created by perforating across the film width before the wrapping step. The invention also concerns a unit for perforating a film.

A device for producing a scoring line in the cylindrical wall of a plastic cup, comprising: a mandrel (8), provided with elements for positioning and retaining a cup applied thereon; a plurality of jaws (24), an end whereof is articulated to the mandrel (8) so as to oscillate on radial planes; respective circular arc-shaped blades (30) being applied to the opposite end of the jaws and being arranged on a plane which is perpendicular to the axis of the mandrel; actuation elements for the jaws being further provided, as well as elements for actuating the mandrel (8) with respect to the actuation means so as to actuate the arc-shaped blades (30) radially from a position which is external to the cup (11) to a position for engaging the wall of the cup at which the blades (30) form a scoring line in the wall.
摘要:
A method for cutting sheet material such as corrugated cardboard (50) with a die cutter (10) so as to reduce the amount of paper dust produced. The die cutter (10) of the present invention utilizes a cutting rule (12) having a base section (14) and a cutting section (16). The cutting rule (12) is characterized by a plurality of serrated teeth (18) extending from the cutting section (16) of the cutting rule (12). Each tooth (18) terminates in a point (22) and has a beveled side face (30). Formed between adjacent teeth (18) is a semi-circular notch (26). The notches (26) extend into the cutting section (16).
