Problems solved by technology

E.g, Figure 2a-Figure 2b When the shown round head-shaped clasp is fastened with the fabric loop, because of its smooth periphery, it does not provide a protruding angle that can hook the fabric loop, causing the effective fastening rate of the clasp to the fabric loop to be biased. Low, but has the disadvantage of insufficient adhesive force
In addition, such round head clasps can only form an effective fastening when the fabric loop is completely inserted into the round head. Although this kind of fastening can provide a very reliable glue fastening, it will not be fastened when it is separated. It is true that the fastened fabric loops will be broken and damaged. Therefore, after several times of use, the adhesive fastening ability of the hook and loop fastener tape and the fabric loops will decrease sharply, or even become useless. No gluing effect, so it has the disadvantage of short service life
[0005] Figure 3a-Figure 3b The elongated oval mushroom head clasp shown provides a higher rate of closure than the round head clasp described above, although it can form effective clasps with fabric loops at both ends of its oval major axis And greater adhesive strength, but, because this type of hook only forms an effective hook with the fabric loop at both ends of its elliptical major axis, it can only be in the direction parallel to the elliptical major axis. Provide effective fastening force, but the effective fastening provided in the direction perpendicular to the long axis of the ellipse is relatively limited
In other words, the gluing effect of this type of clasp and the fabric loop is directional, and cannot provide omnidirectional, non-directional and uniform gluing effect.
Therefore, when the fastening of this type of clasp and the fabric loop is subjected to an external force in a specific direction (for example, a direction perpendicular to the direction of the long axis of the ellipse), it will cause accidental loosening, resulting in this type of clasp The problem of insufficient reliability of components

Embodiment Construction

[0021] now refer to Figure 4 and Figure 5 The illustrated embodiment is used to illustrate the method of the present invention and the manufactured mushroom-head hook-and-loop fastener.

[0022] Figure 4 It is a schematic diagram showing a hook and loop manufacturing apparatus 10 for implementing the method of the present invention. The device 10 mainly includes a rotatable mold roll 20 , an extruder 30 , a stripping roll 40 and a pair of pressing rolls 50 and 52 . The mold drum 20 has a plurality of roughly Y-shaped mold cavities 22 formed on its outer peripheral surface and a cooling device (not shown), such as a cooling water circulation system, is provided inside the mold drum. The extruder 30 includes a melt chamber 32 surrounded by a heating coil 33, a feed barrel 34 disposed at one end of the melt chamber and an injection barrel operably connected to the other end of the melt chamber. The injection nozzle 36 is disposed adjacent to the outer peripheral surface of...

Abstract

The invention provides a method for manufacturing a linking tape and the manufactured linking tape. The linking tape is a mushroom head fastening linking tape. The method of the invention comprises the following two stages: in a first stage, manufacturing the linking tape on which a plurality of clasp prototypes with substantially V-shaped free ends are formed; and then in a second stage, wheel-pressing the V-shaped free ends of the clasp prototypes of the linking tape into substantially polygonal head ends through wheel-pressing processing so as to form the mushroom head fastening linking tape which has high buckling efficiency, long service life, capability of providing a directionless uniform linking function, and high reliability.

Description

technical field [0001] The present invention relates to a method for manufacturing a hook and loop fastener, more specifically to a method for manufacturing a hook and loop fastener with mushroom head fasteners and the manufactured hook and loop fastener with mushroom head fasteners. Background technique [0002] Hook-and-loop fasteners are a known type of fasteners and are widely used in various fields requiring fastening, such as clothing, backpacks, wire management, and the like. Hook and loop fasteners are mainly composed of a Velcro tape with multiple fasteners formed on it and a fabric belt with multiple fabric loops formed on it, and through the engagement / separation of the fasteners and the fabric loops To achieve the effect of sticking / detaching. [0003] Such as Figure 1a with Figure 1b As shown, the manufacturing method of the hook and loop generally includes: adding thermoplastic raw material 1 into the plastic extruder 2; In the mold cavity 4 on the top; af...
