A primary cutting machine that cuts the front end of the object to be cut protruding from the supply box into a rod-shaped body, and a gutter-shaped receiving portion that is located at the lower front part of the supply box and that receives the rod-shaped body cut by the primary cutting machine. And a secondary pusher that pushes the rod-shaped body in the receiving portion toward the outlet of the receiving portion at a constant pitch, and a secondary pusher that cuts the rod-shaped body at the outlet of the receiving portion that protrudes from the outlet at a constant pitch. A two-stage cutting device including a cutting machine is provided.

In addition, a horizontal push slide that presses one side of the cut object near the front end of the supply box to narrow the width of the front end of the cut object, and a presser foot that presses the top of the cut object whose width has been narrowed by the horizontal push slide. Also provided with slides.

[Action]

Since the present invention has the above-mentioned configuration, the mat-like object to be cut is put into the supply box under the condition that the primary pusher is most retracted.

Next, after the primary pusher advances by one pitch, the lateral push slide works to narrow the width of the front end of the cut object, and then the holding slide descends to press the upper part of the front end of the cut object.

In this way, the primary cutting machine operates to cut the front end of the cut object under the condition that the front end of the cut object is compressed by the lateral push slide and the press slide.

The primary cut material that has been cut into a rod shape enters the receiving section,
A secondary pusher at one end pushes one pitch to the outlet and cuts by a secondary cutting machine to form a short secondary cut.
