ABSTRACT:
A die for use in heat welding a plastic motif to a textile base as a first welding ledge extending along a first, substantially planar face of the die, the welding ledge having a coplanar welding surface lying at least 4 mm. above the die face and having a cutting edge projecting above the welding surface to a height of at least 0.3 mm. The width of the welding surface is not less than 0.5 mm and is preferably between 1.5 mm and 3 mm. The die also has further welding ledges on which the welding surface extends the full width of the ledge. Each welding surface serves to weld the plastic material to the textile while the cutting edge severs excess material from the plastic motif along a welded line.
