Abstract
On-loom fabric inspection system (500) including an imaging device (522) configured to collect images of a weaving area (518) of a loom (502). An image-capture trigger-mechanism (529) triggers the imaging device (522) to capture images at required instants during the weaving cycle. An image processor (524) receives data from the imaging device (522) and further detects irregularities in the data.
Claims20
An on-loom fabric inspection system (500) comprising:
- at least one imaging device (522) configured to collect images of at least one section of a weaving area (518) of a loom (502);
- at least one image-capture trigger-mechanism (529) operable to trigger said imaging device (522) to capture an image at a required instant during the weaving cycle;
- and
- at least one image processor (524) configured and operable to receive data from said imaging device (522) and further to detect irregularities in said data,
- wherein
- said image-capture trigger-mechanism (529) comprises at least one heald detector (528) configured and operable to detect relative positions of at least two heald frames (508A, 508B) of said loom (502).

A method for inspecting woven fabric comprising:
- providing at least an on-loom fabric inspection system (500) including:
- at least one imaging device (522) configured to collect images of at least one section of a weaving area (518) of a loom;
- at least one image-capture trigger-mechanism (529) comprising at least one heald detector (528);
- and

- selecting a required instant during the weaving cycle;
- said at least one heald detector (528) detecting relative positions of at least two heald frames (508A, 508B) of said loom (502);
- said at least one image-capture trigger-mechanism (529) triggering said imaging device (522) at said required instant during the weaving cycle;
- said at least one imaging device (522) capturing an image of at least one section of a weaving area (518) at said required instant;
- transferring image data to said at least one image processor (524);
- and
- said at least one image processor (524) analyzing said image data for irregularities indicative of weaving faults.
