Abstract A curtain heading tape for use with draw curtains or the like, the tape having pockets on one face and at least three draw cords in the tape. The pockets are spaced in rows at different transverse distances from the edges of the tape, whereby the tape can be attached to a curtain at different specific heights of the curtain above the level of the suspension hooks.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 147 words
A curtain heading tape comprising an elongate body part having edges, three spaced rows of pockets at different transverse distances from said edges of the tape, said pockets being staggered along the length of said body part so that each adjacent pocket in each set of three pockets is disposed in a different row of pockets, said body part being comprised of vertically spaced single and double picks of weft thread and having a warp density between said pockets greater than the warp density of said pockets, a draw cord through each of said rows and a catch thread attached to successive loops of said double picks of warpwise directed yarn, the said catch thread being warpwise oriented along one selvedge of the tape, whereby when the tape is attached to a curtain different specific heights of curtain above the level of suspension hooks can be provided.
Claim 2
Dependent Claim 147 words
A curtain heading tape comprising an elongate body part having edges, three spaced rows of pockets at different transverse distances from said edges of the tape, said pockets being staggered along the length of said body part so that each adjacent pocket in each set of three pockets is disposed in a different row of pockets, said body part being comprised of vertically spaced single and double picks of weft thread and having a warp density between said pockets greater than the warp density of said pockets, a draw cord through each of said rows and a catch thread attached to successive loops of said double picks of warpwise directed yarn, the said catch thread being warpwise oriented along one selvedge of the tape, whereby when the tape is attached to a curtain different specific heights of curtain above the level of suspension hooks can be provided.
Claim 3
Dependent Claim 29 words
A curtain heading tape as claimed in claim 1 in which a first weft is provided for said body part and a second weft is provided for said pockets.
Claim 4
Dependent Claim 45 words
A curtain heading tape as claimed in claim 1 in which there are three rows of pockets, a group of warp yarns for each row of pockets, each group of yarn being woven successively with a pocket weft yarn and a body forming weft yarn.
Claim 5
Dependent Claim 20 words
A curtain heading tape as claimed in claim 3 in which the pockets are woven 1 and 1 plain weave.
Claim 6
Independent Claim 132 words
The method of producing a curtain heading tape comprising shedding a group of warp yarns, inserting a catch thread into the shed wrapping a warpwise directed yarn by said catch thread and drawing said warpwise directed yarn across said shed to become weftwise oriented, said catch thread becoming warpwise oriented along one selvedge of the tape body, inserting weft into shed formations by a plurality of warp yarns to weave a pocket of a first row of pockets and subsequently weaving pockeTs of at least one row of pockets parallel to said first row of pockets, shedding at least three draw cords with said weft yarns and retaining said draw cords in said tape by weaving them with said yarn that has become weftwise oriented at predetermined positions in said tape body.
Claim 7
Independent Claim 132 words
The method of producing a curtain heading tape comprising shedding a group of warp yarns, inserting a catch thread into the shed wrapping a warpwise directed yarn by said catch thread and drawing said warpwise directed yarn across said shed to become weftwise oriented, said catch thread becoming warpwise oriented along one selvedge of the tape body, inserting weft into shed formations by a plurality of warp yarns to weave a pocket of a first row of pockets and subsequently weaving pockeTs of at least one row of pockets parallel to said first row of pockets, shedding at least three draw cords with said weft yarns and retaining said draw cords in said tape by weaving them with said yarn that has become weftwise oriented at predetermined positions in said tape body.
