Definitions
- ABSTRACT A slide fastener of the concealed or masked type having a pair of similar stringer tapes carrying along respective longitudinal edges :1 row of interlocking fastener elements.
- the stringer tape consists of a Warpknit structure having a web portion and a marginal edge portion interconnected by an interwale groove which defines an axis of fold along which the tape is folded on itself and which is greater in width than the rest of interwale grooves.
- This invention relates to slide fasteners, more particularly to a slider-operated fastener of the concealed or masked type which in its closed disposition substantially simulates a garment seam.
- Slide fasteners having two rows of interlocking fastener elements formed from a continuous filament or wire and secured to respective folded edges of opposed stringer tapes are well known, and such fasteners when closed by the slider mask the elements from external view, only leaving a linear scam in the junction of the opposed tapes.
- the so-called concealed" slide fasteners of known type are designed to maintain the effect of concealing or masking the fastener elements by folding the respective element-carrying edges of stringer tapes on themselves about the sewn seam which secures the respective row of fastener elements to the tape and which extends longitudinally of the tape and outermost of the elements or close to the coupling heads thereof.
- Such known concealed type slide fasteners include stringer tapes of a warp-knitted structure having on one surface alternate longitudinal wales and interwale grooves, with fastener elements mounted on the other flat surface along the respective longitudinal edges of the tapes which are folded,
- fastener elements mounted on the other flat surface along the respective longitudinal edges of the tapes which are folded.
- the present invention provides a concealed slide fastener comprising a pair of stringer tapes formed of a warp-knit structure and carrying rows of fastener elements along their respective longitudinal edges, each of said stringer tapes having on one surface a multiplicity of longitudinally extending alternate wales and interwale grooves. a particular one of said interwale grooves located immediately adjacent the coupling heads of the fastener elements being greater in width than the rest of interwale grooves and serving as a longitudinal axis of fold along which the stringer tape is folded on itself.
- FIG. 1 is a transverse sectional view of a concealed slide fastener stringer provided in accordance with the invention, the chain-dot line representing the unfolded position of the stringer tape;
- FIG. 2 is a transverse sectional view of the fastener stringer with its element-carrying edge held erect for sewing the fastener to a garment fabric.
- a concealed type slide fastener 10 which essentially comprises a pair of similar stringer tapes 11 (but for purposes of illustration, one of such tapes is shown) and a row of interlocking fastener elements attached to the respective tape. More specifically, the row of elements 12 in the form of a spring coil is secured by means of sewing threads 13 to and along a longitudinal edge of the tape 11 and through the medium of a filler cord 14 inserted longitudinally through the space between opposed legs 12a, 12b of the elements 12 in the usual manner.
- the stringer tape 11 is provided with a web portion 11a having on one surface a multiplicity of alternate wales l5 and interwale grooves 16, while the other surface of said portion is rendered flat, on which the row of elements 12 is mounted.
- a tape of this structure is preferrably formed by warp knitting for example with use of longitudinally extending chain stitches which form the wales l5, tricot stitches and transversely extending lapping threads laid in coursewise to interconnect the chain stitches, with the grooves 16 formed longitudinally between adjacent wales 15.
- the stringer tape 11 is provided with a longitudinal marginal edge portion 11b contiguous to the web portion 11a for mounting thereon a row of fastener elements 12, the two portions being interconnected by an interwale groove 16 which is greater in width than the rest of grooves 16.
- the selected interwale groove 16' which lies immediately adjacent the coupling heads of the fastener elements 12 is utilized as a longitudinal axis of fold along which the tape 11 is folded on itself in the known manner to conceal or mask the row of fastener elements 12 when the fastener 10 is closed by a slider not shown.
- the sewing needle 17 is allowed to pass precisely through and along the groove 16 without interference by adjacent wales 15 on opposite sides of the groove 16', so that there can be obtained a neatly arranged line of stitching 18 within the groove 16 which secures the fastener 10 to a garment fabric 19.
- the tape 11 can be alternate wales and interwale grooves, a particular one of said interwale grooves located immediately adjacent the coupling heads of the fastener elements being greater in width than the rest of interwale grooves and serving a longitudinal axis of fold along which the stringer tape is folded on itself.
