Abstract
A ladder tape and a method of making the ladder tape are disclosed in the present invention, wherein, by using a knitting technique, at least two warps and at least one weft generate a knitting structure with chains on a front surface of a first band and a second band, which have the same width, and generate threading segments on a rear surface of each of the bands to bind the weft. Whereby, the resultant knitting structure has no discontinuous opaque shades, and the problem of unwanted light leakage can be avoided as well.
Claims7
A ladder tape, comprising:
- a first band and a second band, each of which has a front surface and a rear surface;
- a first warp and a second warp, each of which interlaces the front surface and the rear surface along a long axis of the corresponding band, wherein each of the warps forms a plurality of threading segments on the rear surface;
- a slit is left between each of the threading segments and the rear surface;
- and
- a weft shuttling between the first warp and a second warp, wherein the weft comprises a plurality of first portions following a S-shaped path to pass through the slits left between the threading segment of the first warp and the rear surface of the first band, a plurality of second portions following a S-shaped path to pass through the slits left between the threading segment of the second warp and the rear surface of the second band, and a plurality of bridging portions, each of which is connected to the corresponding first portion and the corresponding second portion with two ends thereof respectively.
2 more elements
A method of making a ladder tape, comprising steps of:
- providing a first band and a second band in parallel, wherein each of the bands has a front surface and a rear surface;
- the first band and the second band are adapted to be pulled in a vertical direction;
- controlling a hook portion of a first crochet needle to move forward and backwards to pass through the first band, and controlling a hook portion of a second crochet needle to move forward and backwards to pass through the second band;
- placing a first warp on the hook portion of the first crochet needle to pull the first warp from the rear surface of the first band to the front surface thereof, wherein the first warp forms a first chain on the front surface of the first band, and forms a plurality of threading segments on the rear surface of the first band;
- and placing a second warp on the hook portion of the second crochet needle to pull the second warp from the rear surface of the second band to the front surface thereof, wherein the second warp forms a second chain on the front surface of the second band, and forms a plurality of threading segments on the rear surface of the second band;
- and
- moving a weft vertically along a S-shaped path to pass through a series of the threading segments of the first warp, pulling the weft across a space between the first band and the second band, moving the weft vertically along a S-shaped path to pass through a series of the threading segments of the second warp, and pulling the weft back to the first warp to continuously pass through another series of the threading segments of the first warp after being moved for a predetermined distance on the second band;
- wherein the weft is repeatedly pulled and moved in such manner between the first warp and the second warp until a knitting is completed.
