ABSTRACT:
The guillotine on a conventional cutter assembly used in conjunction with an eavestrough-forming machine has been modified to produce compacted cut-offs and to prevent jamming of the cutter assembly.
A radius is formed in the upper end of each cutting edge of a V-shaped blade. In a preferred embodiment a second, more steeply inclined portion connected at its top end to the radius is provided along each cutting edge.
