Embodiment Construction

[0121] Based on typical embodiments, embodiments of the present invention will be described in further detail below with reference to the drawings.

[0122] figure 1 with 2 A top view and a sheared end of a main embodiment of the invention are schematically illustrated, respectively. The zipper tape 10 has a flat substrate 11 and engaging elements 12 consisting of a plurality of hook elements protruding from the engaging surface of the substrate 11, and the zipper tape 10 also includes a row of magnets 13 protruding from the surface of the substrate 11 , and roughly arranged below the centerline of the zipper tape 10 . The magnet 13 is composed of many magnetic protruding portions 13a made of a synthetic resin material in which magnetic particles 14 are mixed, and located in the raw material portion 13c of the substrate 11 below these protruding portions 13a. The particles 14 are mixed, and the magnetic particles 14 are not dispersed throughout the substrate 11 . Therefor...

Abstract

The present invention provides a fastener strip having magnetic powders not distributed through the entire volume thereof and contained in individual discontinuous identification areas thereof. This fastener strip has a substrate and many hook elements rising from an engaged surface of the substrate, and further has a magnetic body in a row, which rises from a surface of the substrate and is disposed below substantially a centerline and / or both lateral edges of the fastener strip. The magnetic particles are injected into the magnetic body and the substrate below the magnetic body, but, they are not dispersed through the entire substrate. The present invention also includes a manufacturing method and a manufacturing device for such a fastener strip. The present invention may function of forming an effective seal not only to accurately and suckingly position the fastener strip at a predetermined position in a metal mold but also to prevent the engaging element from being contaminated.

Description

technical field [0001] The present invention relates to the field of engaging / disengaging tools, and in particular, the present invention relates to a fastener tape having magnets distributed not through its entire volume, but distributed in Individual discrete recognition regions, . Background technique [0002] For example, a thin plate or the like for a motor vehicle is made with a cushioning body structure in which a skin material is covered on the cushioning body, and ergonomically adopts a structure having a concave shape that satisfies the condition for maintaining a sitting posture and You won't get tired after sitting for a long time. In this concave plate, in order to prevent the skin material from coming off from the buffer body of the concave part, by using such as Figure 34 Shown has the foam molding article that is fixed on the recessed portion 10 as buffer body 9, and the zipper tape 10 that is integrally formed on the buffer ...
