One of the latest trends is low-density velour carpets, carpets with very low pile. Traditional velour looms can weave very fine high-density carpets but only at rather low productivity levels. That makes these carpets too expensive for the consumer who just wants to follow the latest trends.
Stäubli ALPHA 500 UNIVERSAL weaving machines enable the weaving of carpets with a pile height of less than 3 mm (the 4 m wide model) and 4 mm (the 5 m wide model), with pile heights similar to traditional velour carpets. By using cotton wefts and a special ground weave structure, these carpets woven on ALPHA are very soft and easy to fold, just like "real" velour carpets.
Weaving carpets with such low pile heights requires lancets in order to preclude the problem of tight pile threads pulling the top and bottom carpets together. In its broad product range, Stäubli offers 6 mm lancets for its double rapier weaving machines, allowing pile heights – before shearing – of less than 3 mm.
Weaving with such a low final pile height, instead of shearing several mm of pile after weaving, is economical: it saves time, energy and yarn.
