Abstract
A tufting machine for creating cut pile carpet with two different pile heights. A knife (20) associated with a respective hook assembly (1), and is reciprocally mounted and inclined with respect thereto. Each hook assembly has upper (6) and lower (7) hooks each having a cutting edge (8, 9) at the lower edge and means (10) for selectively directing the yarn onto one of the upper and lower hooks. The knives (20) each have a single cutting edge (21) arranged to co-operate with both the upper (6) and lower (7) hooks to cut each loop of yarn seized by a respective hook assembly with a scissor action. Relief (22) is provided between the knife and the lower hook allowing the knife to clear the lower hook (7) when the knife cutting edge (21) approaches the upper hook cutting edge (8).
