PURPOSE: To perform the appropriate carry-in of bundle material to a bundle cutter so as to heighten the bundle cutting work efficiency of the bundle material by providing carrier rollers in such a way as to protrude/recede in relation to the placing height positions of specified placing parts at the time of positioning the specified placing parts in a carrier region.

CONSTITUTION: Long-sized bundled plates W are placed in plural placing parts of endless chains 35 in a chain conveyor device 9. The endless chains 35 are then put in travel motion in the feed direction to position the specified placing parts in a carry-in region, and carry-in rollers 21 are protruded in relation to the placing height positions of the placing parts. The specified bundled plates W are carried to a bundle cutter 1 by these numerous carrier rollers 21 so as to perform bundle cutting to the bundled plates W. After taking out bundled products, the bundled products are carried out in the carry-out direction by a product carry-out device and stocked in the stock part of a product stock conveyor device.
