Abstract: The invention relates to a machine for the manufacture of a non-slip fabric, comprising: a drum made to rotate around its own axis with a number of cup-shaped seatings on its surface, which seatings communicate with the inside of the drum, the inside of the drum being maintained at a pressure lower than atmospheric pressure; an extrusion head designed to extrude a thin plastic film onto the surface of the said drum; a second head, downstream of the previous one, designed to extrude a second, flat layer of thin plastic film; systems designed to bond the said films on the surface of the said drum; systems designed to convey a strip of fabric and bond it to the said films around the said drum; systems designed to cool the surface of said drum; systems designed to remove the laminate so obtained. The invention relates also to the relevant manufacturing method.
Abstract: A cooling device for texturized yarns comprises a rotating drum equipped with a perforated wall, a unit capable of depositing the yarn exiting from a texturizing nozzle on the perforated surface, and a device capable of aspirating air from the inside of the drum, and elements are provided capable of circulating a refrigerating fluid inside the drum as well as elements, external, with respect to the drum, adapted to cool the air that is aspirated through the holes of the drum to cool the yarns.
Abstract: A three layer, non-slip fabric has an upper fabric layer which is bonded through an intermediate flat plastic layer to a lower plastic layer having cup-shaped elements distributed therelong. Each cup has sidewalls and an outwardly concave end wall with one or two holes in the wall to allow the cups to deform.
