Abstract
A device to remove any bias in the position of a cut line on a continuous strip of cloth. The device has at least two detecting devices located along a predetermined path to detect the position of the cut line and a straightening bar to tilt the continuous strip to compensate for the bias.
Claims9
A bias correction device to remove any bias in the position of a cut line on a continuous strip of cloth as said continuous strip of cloth advances along a predetermined path, comprising:
- at least two detecting devices located along said predetermined path to detect any bias in said position of said cut line;
- a straightening bar mounted on said predetermined path to tilt said continuous strip in the opposite direction to said bias to compensate for said bias.
A bias correction device to remove any bias in the position of a cut line on a continuous strip of cloth as said continuous strip of cloth advances along a predetermined path, comprising:
- at least two detecting devices located along said predetermined path to detect any bias in said position of said cut line;
- a straightening bar mounted on said predetermined path to tilt said continuous strip in the opposite direction to said bias to compensate for said bias;
- and
- an edge guide apparatus located on said predetermined path to ensure that the edges of said continuous strip maintain their position along said predetermined path, said edge guide apparatus comprises two or more rotating wheels that ride along said edges in said continuous strip.
A bias correction device for a textile strip with cut lines thereon forming discrete panels, comprising:
- means for moving said textile strip along a predetermined path having lateral boundaries;
- means for detecting any bias in the position of said cut lines on said textile strip with respect to a line perpendicular to said predetermined path;
- and
- straightening means positioned along said predetermined path to reorient said textile strip to maintain said cut lines in alignment with said line perpendicular to said predetermined path;
- whereby any bias in said cut lines as determined by said detecting means is eliminated.
