摘要
There is provided a method of deforming the hook head portions of hook elements on a web backing. The hook elements on the web backing are fed into a nip formed between a support surface and an upper heated surface having a durameter hardness of less than 90 Shore A. This upper heated surface compressively engages the hook head causing it to turn down and permanently deform. This increases the uniformity of the hook head elements forming a fiber engaging crook region.
