Abstract
A method and means are disclosed for measured control of tape-like warps for shedding and taking-up operations when producing woven materials comprising tape-like warps and wefts. According to this invention, a displaceable contact surface of the warp control device is located between the warp supply source and the shedding device. The warp control device includes a displaceable member for providing contact surface to displace at least some of the tape-like warp for releasing them in a measured way for shed forming and taking-up operations. Further, the contact surfaces are retracted for enabling shed closing and measured taking-up.
Claims15
An apparatus for producing a woven material from tape-like warps and wefts comprising:
- a warp supply source for tape-like warps;
- a shed forming device to form a shed by said warps;
- a weft insertion device for inserting tape-like weft in the shed formed by said warps;
- and
- a take-up device for taking-up the produced woven material;
- wherein the apparatus further comprises a warp controlling device located in a warp path from the warp supply source to the shed forming device, said warp controlling device comprising at least one displaceable contact surface, being displaceable in a thickness direction of the tape-like warps, and an arrangement to displace the contact surface for displacing at least one of the warps between the warp supply source and the shed forming device without any clamping of the tape-like warps, whereby the displacement of said warp(s) releases them from the warp supply source for shed opening and taking-up, and to retract the contact surface for enabling shed closing and fabric taking up.
A method for producing a woven material from tape-like warps and wefts comprising:
- providing tape-like warps from a warp supply;
- forming a shed by said warps;
- inserting tape-like weft in the shed;
- and
- taking-up the produced woven material;
- displacing at least one contact surface which is being in contact with at least some of the tape-like warps, in a thickness direction of the tape-like warp, for displacing at least some of the warps without any clamping, to release warp from said warp supply for shed formation and taking up;
- and
- retracting said displaced contact surface for enabling shed closing and taking-up.
