Definitions

  • This invention relates to self-gripping fasteners, i.e. , to articles which have two separate parts, each of which is provided on one face with fastening elements which are complementary to fastening elements carried by one face of the other part.
  • This invention relates self-gripping fasteners of the type wherein one part is formed by a tape or a band intended to cooperate by its fastening elements with the fastening elements carried by the complementary part of the fastener.
  • the complementary part of the fastener is preferably formed of the same type of material, or may be in the form of a web, for example, a covering.
  • Tapes of type general type to which the invention relates usually have a rectilinear shape since, in most cases, a rectilinear shape for the fastening or gripping zone is sufficient.
  • such tapes are usually woven on narrow fabric looms, so that the resulting product is inherently linear, with parallel longitudinal sides. Such woven tapes do not have sufficient deformability to function in the manner of the invention disclosed in this application.
  • the tape when in its use position, should preferably have a non-rectilinear shape, for example, curved or sinuous, while remaining in a single plane.
  • a non-rectilinear shape for example, curved or sinuous
  • the self-gripping tape is cut according to the desired shape from a self-gripping web or sheet. This is costly in terms of labor and requires many precise cuts in order to create an appropriately-shaped product. In addition, tapes which are cut according to one given shape cannot be used for another shape. Finally, cutting shapes in this manner results in substantial waste.
  • patches of a self-gripping tape can be cut and then attached to a support which can be deformed in its plane or is both rigid and previously shaped. This solution is also costly.
  • the fastener can be made of a tape, the base of which carrying the fastening elements is constructed of longitudinal elastic yarns. This solution is extremely costly due to the price of these elastic yarns.
  • the invention includes a self-gripping tape which comprises a base and fastening elements carried by the base and which is characterized in that the base is a knitted fabric which is flexible and deformable in its own plane.
  • a self-gripping tape is provided wherein the tape may be deformed while the tape is in its own plane to give it any desired shape without generating undesirable folds, without requiring costly labor and without cutting the tape into the desired shape.
  • the tape can be shaped from a rectilinear length of tape. This tape is inexpensive since it is knitted with an ordinary, inelastic yarn.
  • the fastening elements are integral with the knitting structure itself and they are filamentary.
  • the fastening elements can be either male or female fastening elements, such as loops, hooks or filamentary elements with enlarged heads.
  • the base is adhered by the side opposite the fastening elements to a supplementary layer.
  • This layer is also deformable in its own plane and may be, for instance, a foam layer.
  • the self-gripping fastener is made according to a method characterized in including the step of flat-knitting a web fabric and then in cutting this web into a plurality of rectilinear tapes, preferably in a continuous manner in the longitudinal direction of the web.
  • This tape 1 is generally classified as a self-gripping fastener, the tape being intended to cooperate in a separable fastening relationship with a complementary part.
  • the tape may be attached to a cover of, for example, an automobile seat assembly, and used to retain the seat dress cover on the foam cushion portion of the seat assembly. See, for example, applicant's prior patent No. 4,693,921.
  • the tape 1 includes a base 2 and fastening elements 3 which are carried by the base 2.
  • the fastening elements 3 are each made of a stem 4 projecting from a face of the base 2.
  • Each of the stems 3 has an enlarged head 5.
  • These enlarged heads 5 may be formed in any one of several ways, such as by thermal fusion of the free ends of the stems 4.
  • the tape 1 is intended to be attached flat to a support, directly or indirectly.
  • the tape 1 may be given any non-rectilinear desired shape in its own plane, and therefore also out of this plane, the tape 1 is arranged, according to the invention, so that its base 2 is made of a knitted fabric which is flexible and deformable in its own plane. This fabric is knitted with a non-elastic yarn, the deformability being the result of the flat knit structure.
  • the tape 1 is attached to its support in a deformed state by any appropriate means, for instance, by adhering, sewing or joining with a foam article, e.g. an automobile seat-rest or back-rest.
  • the tape base 2 by its face opposite to that which carries the fastening elements 3, is adhered to a supplementary flexible layer 6, also deformable in its own plane and made, for instance, of foam.
  • the fastening elements 3 belong to the knitting structure itself, i.e. , they are obtained in their final shape or in an intermediary shape during the knitting step itself of the base 2.
  • the tape 1 is obtained from a flat-knitted rectilinear part which is then out into a plurality of rectilinear tapes.
  • a plurality of tapes is thus obtained in an economical manner from a single knitted web.
  • the fastening elements of the tape according to the invention are filamentary. These fastening elements, depending on the uses of the tape, can be male or female elements, or with enlarged heads, as described above.
  • the fastening elements are male elements.
  • the fastening elements 3' are also of male type, and they are constituted by hooks while, in the alternative of Fig. 4, the elements 3" are of the female type, for example, loops.
  • the fastening elements 3' and 3" of Figs. 3 and 4, respectively, are preferably part of the knitting structure of the fabric base 2.
  • the fastening elements 3" are obtained directly in their final shape by knitting, while the fastening elements 3' are each obtained by an additional step of cutting a loop.
  • Fig. 5 illustrates a method according to the invention for manufacturing the above tape 1.
  • a relatively wide web 7 is first knitted in a flat-knitting machine (not shown), the web 7 being up to several meters in width.
  • the knitting direction is shown by arrow A and the web 7 is shown broken-away or interrupted both in the longitudinal direction A and in the width direction.
  • the web 7 is then cut along parallel rectilinear cutting lines 8 to give rectilinear tapes which form the tapes 1 in the manner described above.
  • the cuts are made in a continuous manner in the longitudinal direction A, so that all of the cut tapes 1 have the same width.
  • the loops are sheared to produce stems.
  • a B A B Needle bar 1 10 11 12 11 Needle bar 2 10 10 01 01 Needle bar 3 11 10 11 12
  • the fabric can also be knitted on a circular knitting machine, but the loop would be oriented as on the pile warp knitting machine (Example 1).
