CUTTER ASSEMBLY FOR EAVESTROUGH - FORMING MACHINE ABSTRACT The guillotine on a conventional cutter assembly used in conjunction with an eavestrough-forming machine has been modified to pro- duce compacted cut-offs and to prevent jamming of the cutter assembly.

In a preferred embodiment a second, more steeply inclined portion connected at its top end to the radius is provided along each cutting edge.
