Definitions
- the invention relates to a method for the production of closure elements for metallic adhesive closures, wherein in a metallic support the contour of interlocking elements to be formed cuts made each leaving a connection line and bending operations are performed to the limited by the incisions areas as Verhakungs institute to as bending lines up the connecting lines from the plane of the carrier. Moreover, the invention relates to a closure element produced by such a method.
- the invention is in view of this the object to provide a method available by means of which a simple, efficient and thus cost-effective production of closure elements for metallic adhesive closures is possible.
- the essential feature of the invention is not only that the complete formation of each interlocking element is carried out by a combined processing step, which comprises both the cutting process and the embossing process causing a bending of the shape, but that the respective combined cutting and stamping process in the run through is guided by the carrier is passed through the engagement portion of intermeshing teeth of bodies of revolution.
- the arrangement is preferably such that at least one of the rotational bodies is rotated by a drive and the carrier in the form of a band is pulled through the engagement region of the toothing by the feed force generated by means of the drive.
- incisions are formed in a rectangular shape, the long sides extend in the direction of the teeth and whose at least one short side is formed by the left connection line.
- a particularly advantageous pattern of the hooking elements can be formed such that adjacent rows of hooking elements they are designed so that the interlocking elements are offset in mutually adjacent rows to each other in the longitudinal direction so that the Verhakungsetti in each but one row after another are aligned.
- the interlocking elements in each row are raised by bending in the same direction around the bending line or that the interlocking elements are raised in mutually adjacent rows with mutually opposite bending directions around the bending line.
- adhesive closures that provide a desired holding force against lifting of the carrier from each other and a defined security against movement against displacement of the carrier.
- interlocking elements in each row are elevated with alternating bending directions around the bendline.
- the invention also provides a closure element produced by the process according to the invention, which has the features of claim 9.
- Fig. 1 is a perspective oblique view of a portion of a
- FIG. 2 is a side view of the portion shown in FIG. 1;
- FIG. 2 is a side view of the portion shown in FIG. 1;
- Fig. 3 is a plan view of the portion shown in Figs. 1 and 2;
- Fig. 4 is a highly schematically simplified drawn perspective oblique view, in which only the part of an establishment is shown to illustrate the sequence of the method according to the invention take place in the means of tooth engagement combined cutting and embossing operations;
- Fig. 5 is a similar to Figure 1 oblique view of a second embodiment of the closure element.
- Fig. 6 is a side view of the portion shown in Fig. 5;
- Fig. 7 is a plan view of the portion of Fig. 5 and Fig. 8 is a partial view similar to Fig. 4 to illustrate the process flow for the production of closure elements with hooking elements in C-shaped hook shape.
- FIG. 4 illustrates the sequence of the method according to the invention for the production of closure elements with hooking elements 1, which have a hook shape, as shown in the examples of FIGS. 1 to 3, where not all interlocking elements 1 are numbered.
- a still undeformed, band-shaped metallic carrier 3 for example, a stainless steel alloy and with a material thickness, depending on the intended use of the closure element to be produced can be 0.1 to several mm, through the region 5 of the toothing engagement between two rotatable, a circumferential toothing having rollers 7 and 9 passed, wherein before and behind the engaging portion 5 guide rollers 11 are arranged.
- At least one of the roller disks 7, 9 is rotatable by means of a drive, so that the carrier tape 3 is pulled through the region 5 by the feed force acting in the engagement region 5, ie is moved to the left in FIG. 4.
- tooth forms and backlash are chosen and matched to one another such that a combined cutting and bending process takes place in region 5 on the initially unprocessed carrier strip 3, in which the teeth of the roller plate 9 perform a kind of punching operation of the in 4 incisions 13, of which only a few are numbered in the figures, are formed in the form of elongated rectangles in the feed direction, wherein the rectangular shape of each because it is closed at connecting lines 15, which extend to the feed direction in the transverse direction and form bending lines about which the respective inner district of the incisions 13 is raised.
- the hooking elements 1 lead to the bending lines, i. H. the connecting lines 15, adjacent to each one to the plane of the carrier tape 3 obliquely extending foot part 19 and an adjoining, curved in the direction of the carrier tape 3 Hakenendteil 21.
- These Hakenendmaschine 21 are numbered only in Fig. 2 and partially in Fig. 3.
- FIGS. 1 to 3 illustrate examples in which six by means of a plurality of adjacent rows of teeth adjacent rows of hooking elements 1 are formed simultaneously.
- the interlocking elements 1 are the same in all adjacent rows, wherein the bending direction in which the interlocking elements 1 are bent about the connecting lines 15, within each row is the same.
- each of the bending direction is reversed, so that the interlocking elements 1, which are aligned with each other in the transverse direction, are the same orientation for every next but one row.
- each of the rectangular incisions 13 is delimited on both short sides by a connecting line 15, only a few of which are numbered in the figures, and the interlocking elements 1 have a C-shaped configuration.
- FIG. 8 clarifies, by the fact that the teeth of the roller disc 9 have a centrally located, transversely extending, projecting cutting edge 23 which engages in a tooth recess 25 in the tooth gaps 17 of the roller disc 7 during tooth engagement, that the carrier tape 3 is severed by the cutting edge 13.
- one partial inner area of each slot 13 can be raised in each case about the one and the other connecting line 15, ie. H.
- each incision 13 there are two interlocking elements 1. These are, in accordance with the shape of the tooth gaps 17 of the roller disc 8, pronounced in C-shape, d. H. they point, starting from the foot part 19 to the hook end part 21, towards a continuous curvature.
- interlocking elements 1 are, in accordance with the shape of the tooth gaps 17 of the roller disc 8, pronounced in C-shape, d. H. they point, starting from the foot part 19 to the hook end part 21, towards a continuous curvature.
- FIGS. 5 to 8 For the sake of clarity of the drawing, not all incisions 13, connecting lines 15, tooth gaps 17, foot parts 19 and hook end parts 21 are numbered in FIGS. 5 to 8.
- FIGS. 5 and 7 illustrate the arrangement and orientation of the C-shaped hooking elements 1.
- the hooking elements 1 are alternately bent in the one or the other bending direction about the connecting lines 15, so that in successive Verhakungs instituten 1 each of the open Sides of the C-shape face each other.
- the interlocking elements 1 in the adjacent rows as in the example of FIGS. 1 to 4 are replaced with respect to one another in such a way that the interlocking elements 1 in each subsequent row in FIG.
- hooking elements 1 Transversely oriented mutually aligned. It is understood that ever According to purpose different patterns of hooking elements 1 can be formed, both as regards the hook shape as well as the orientation and dimensioning in terms of hook width, hook length, repetition frequency in the hook rows and the like.
