Machine to join or tape two edges (11a, 11b) of a fabric (11) by means of adhesive (13, 17) comprising a welding unit (14) to which the two edges (11a, 11b) of fabric (11) are fed, adjacent or one overlapping the other, along a determinate work plane (P), which is suitable to melt the adhesive (13, 17) exerting a pressing on the edges (11a, 11b) in order to determine the operation of joining or taping of the two sides (11a, 11b). The welding unit (14) comprises:
a first welding device (16) disposed above the work plane (P) and comprising a first tape (34), a first movement unit (30) to move the first tape (34) and a first heating unit (26) to heat the first tape (34); a second welding device (18) disposed under the work plane (P) and comprising a second tape (36), a second movement unit (33) to move the second tape (36) and a second heating unit (28) to heat the second tape (36). A support arm (20) is disposed under the work plane (P), the second welding device (18) is assembled inside the support arm (20). The support arm (20) comprises cooling means (46) suitable to cool its external surface which, during normal use, would be heated by the second heating unit (28) of the second welding device (18). |
