Knitting substrates for roofing felts
Short notice given only substantially as follows: A circular knitting machine designed to make substrates for use in bitumen-impregnated roofing felts is the subject of US Patent 6370921 granted to V2 Composite Reinforcements Inc of Auburn.The intention is that the knitted fabric is opened and laid up as a two-ply reinforcement made from fibres such as glass or glass roving. The machine is supplied with stitching yarns from a cylinder having a series of axially arranged holes around its circumference. Latch needles pass through these holes and each pair of adjacent needles defines an interstitial space. An end of yarn is supplied radially and corresponds to each interstitial space between the needles. A second yarn is introduced to the cylinder at an insertion point and at least one such yarn is introduced tangentially to the cylinder at the feed point. The cam system and the two feeds are rotated stepwise, sequentially relative to the cylinder.
