Definitions

• the object of the present invention is to remedy the above trouble and to obtain, with a fastening device of the type described above, a stronger adherence of the two tapes, one to the other, requiring however the manufacture of only one tape comprising loops and hooks.
• the fastening device according to the invention is characterized by the fact that each tape comprises a multitude of loops forming a carpet of determined thickness and a multitude of hooks protruding from the loop carpet.
• Such a fastening device thus provides for doubling the hooking effect, compared to those devices of the type presently commercially sold under the trademark Velcro, since in the case where a same number of hooks is arranged on each tape per square centimeter, the fact of applying two identical tapes one against the other creates a doubled amount of hooking points between both tapes.
• FIG. 1 is a diagrammatic vertical sectional view, at large scale, of a tape embodying the present invention
• FIG. 2 shows the engagement of the hooks and loops of two tapes such as shown in FIG. 1 applied one against the other;
• FIG. 3 is a plan view of the tape of FIG. 1.
• this fastening device of two elements comprises two tapes 1 each comprising a base sheet 2, woven, molded or laminated, on one face 3,387,345 Patented June 11, 1968 of which a multitude of loops 3 are arranged and forming a homogeneous carpet.
• the loops 3 are preferably made of multifilament yarns in the same way as for an astrakhan fabric and preferably of synthetic material such as polyamides, including nylon, or other heat-settable or other thermoplastic materials.
• the base 2 also comprises hooks 4, preferably made of monofilament yarn, for instance, of synthetic material.
• Such hooks 4 may be made out of monofilament loops of synthetic material, e.g. polyamides such as nylon or other heat-settable or thermoplastic material, which might be stabilized by thermal treatment for their final shape, these loops being cut afterwards on one of their sides to form hooks 4 having a bent over end 5.
• the hooks 4 protrude from the loop carpet 3. It is even desirable that the hooks protrude by a sufficient height above the loop carpet 3 so their end 5 bent over towards the loop carpet 3 be located above the latter.
• the monofilament hooks 4 having a higher stiffness compared to the loops 3 easily penetrate into the opposite loop carpet 3 to be hooked with the loops.
• the number of hooking points between the two tapes 1 is doubled per surface unit with respect to the one that would be obtained if a tape provided only with hooks 4 of same density was combined with a tape only provided with loops 3.
• the manufacture of the tape may be in accordance with the disclosure of US. Patent 3,009,235 to De Mestral except that the loop pile as well as the hook pile is woven into the same base sheet with the hook pile extending higher with respect to the base sheet.
• FIG. 3 shows the aspect in plan view of such tape 1, the general surface of which is covered with loops 3 forming a continuous carpet out of which the hooks 4 protrude.
• these hooks 4 on base 2 they may be arranged in chevrons as shown on FIG. 3. Such arrangement is generally obtained when the hooks 4 are formed during weaving of base 2, by arranging the monofilament yarns intended for the books 4 on lancets, to pass back and forth over the same, in the course of weaving.
• these tapes 1 are provided with threads being preferably made of synthetic material.
• the hooks 4 of these tapes could be metallic rather than synthetic.
• Adhesive fastening device comprising two flexible tapes (1), having base sheet (2) at least one of the tapes having on one surface of the base sheet thereof hooking means in the form of loops (3) and hooks (4), the hooks (4) of said one tape (1) being adapted to engage in loops of another tape when in fastening position, characterized by the fact that at least said one tape (1) comprises a multitude of loops (3) forming a carpet of determined thickness and a multitude of hooks (4) protruding from the carpet of loops (3).
