ABSTRACT:
A double welt trimmer for removing the excess edge from a double welt comprising a housing, a passageway through the housing to permit the passage of the double welt therethrough, a cutter assembly mounted on the housing and having a cutting blade associated therewith, and being disposed immediately above the passageway so as to cut the excess edge from the double welt when the latter is pulled through the passageway. In one form of the invention, a piece of sponge rubber or plastic material urges a slotted block containing the passageway towards the cutter assembly. The welt material is pulled through the slot in the block and an aligned notch in the housing. In another form of the invention, the cutter assembly is mounted on the top of the housing by means of a pair of bolts which pass into the interior of the housing. The double welt material is pulled through a slot in the housing under the cutter sub-assembly. Springs mounted on the bolts urge the cutter assembly downwardly into engagement with the double welt material as it is pulled through the slot.
