Abstract

PURPOSE:To prevent damages through the detection of shear of materials, by detecting the thickness of materials by a plate thickness detector and detecting the presence or absence of materials by a area detector provided around the plate thickness detector. CONSTITUTION:If a blank B is fed to a multiplex blank station II, when it stops at B1, the spindle of a plate thickness detector 11 measures the plate thickness and the delivery of one sheet is detected. The plate is fed to the next idle station III, as it is. If two or more blanks are fed overlapped without shear, the detector 11 detects a multilayer blank, which is discharged externally to outside the carrying path at the discharge device. If two or more blanks are fed with shear, proximity switches SW6, SW10 are on, a relay is operated to produce a alarm, and a magnet belt feeder 6 is stopped, allowing to prevent damages.
