ABSTRACT:
A paper comminuting device or similar device, such as a paper shredder, is composed of two dimensionally stable side components extending parallel to each other and a bottom and a rear wall connecting the side components, and a cutting mechanism housing releasably placed on the side components and the rear wall. The rear wall and the bottom of the base frame are manufactured from an initially single-piece, planar plate with a transversely extending bending groove between the areas of the bottom and the rear wall. When the base frame is assembled, the appropriately profiled side components are connected to the plate and hold the plate in an angular position of 90 degrees. The side components are connected through insertable connecting points to the cutting mechanism housing so as to form together with the cutting mechanism housing a rigid, box-like component, wherein the connecting points are arranged in at least two planes located at a vertical distance from each other.
