Abstract
A modular comb element for a machine for automatically cutting a mat of sheets of material. The cutting machine includes a plurality of cutting supports. The comb element includes a plate forming a support from which a first and a second row of teeth extend longitudinally. The teeth of the first row alternate with the teeth of the second row, and a free end of the teeth of the first row are farther from a downstream edge of the support than a free end of the teeth of the second row of teeth. A ramp is mounted on the downstream edge of the support and inclined with respect to the latter so as to limit the contact surface between the mat of sheets and the comb element. Air injection means are at a downstream edge of the ramp over an entire width thereof.
