The strict quality control standards insisted upon by their clients mean their manufacturing process is both high-tech and high precision. This ensures consistency across any and all batches of the same liner or carpet. The quality control task identified involved squares of carpet up to 2m x 2m being measured for thinness or where the pile of the carpet was below a minimum thickness.

Test Solution

By presenting a bright light behind a test sample of carpet, clusters of pin-hole light become visible in any areas where the weave is not close enough or the pile not thick enough. This can be manually inspected by a technician by getting up close to the surface and moving across in a logical grid pattern. Alternatively a faster solution is to photograph the sample from a set distance and use software to help identify inconsistencies.

Customer requirements

Our Brief

• - To produce a fully adjustable light table which allows inspection of single carpet blanks.
• - The light must be intense enough to clearly shine through thin areas of carpet.
• - Retaining clips will be required to secure the blanks when the table surface is angled.
• - The table must incorporate a boom or camera mounting pole so that a high resolution photograph of the carpet can be taken at approximately 1.8m above the surface of the table.
• - The light table must be switchable in two halves (left / right)
• - Adjustment for night and angle must also be possible.
