Machine for the manufacture of a non-slip fabric

A machine for manufacturing a non-slip fabric, comprising:

• a cylindrical drum having an interior, an axis, an inner surface, and an outer surface;
• a plurality of cup-shaped seatings on the outer surface, each seating having at least one hole therein, for communicating each seating with the interior of the drum;
• means for rotating the drum around its axis;
• means for maintaining the interior of the drum below atmospheric pressure for drawing air through the holes in the seatings and into the interior of the drum;
• a first extrusion head for extruding a first thin plastic film onto the surface of the drum, the seatings with the means for maintaining the interior of the drum below atmospheric pressure, forming cups in the first thin plastic film;
• a second extrusion head which is downstream from the first extrusion head with respect to the direction of rotation of the drum, for extruding a second thin plastic film onto the first thin plastic film;
• means for conveying a strip of fabric onto the second thin plastic film at a location downstream from the second extrusion head;
• means for simultaneously bonding the strip of fabric to the first and second thin plastic films to form a bonded laminate on the surface of the drum;
• means for cooling the outer surface of the drum to allow easy removal of the laminate from the drum, wherein said means for cooling defines an exterior surface adjacent to the inner surface of the drum, said means for cooling comprising a series of elongated and parallel channels for circulating a coolant, the channels being formed on the exterior surface of the cooling means;
• and
• means for removing the bonded laminate from the drum downstream of the means for simultaneously bonding.
