要旨とするものである。Conventionally, in this type of cutting device, the height from the cutting edge to the top surface of the pedestal was longer than the length of the finished product, making it impossible to collect the products in an orderly stack. The type with a fixed pedestal with a short head can be stacked, but the corners may be bent and fall apart, and there are defects such that only a small number of stacked sheets can be recovered. The present invention attempts to eliminate the above-mentioned defects by causing the pedestal to gradually lower in small steps each time a predetermined number (depending on the height) of cut products are accumulated on the pedestal. A cutting device blade section consisting of a movable upper blade and a fixed lower blade that shreds the intermittent feed original fabric while stopped, a space formed in front of the fixed lower blade for collection of cut products, and the same space. A pedestal with a stopper for abutting the cut product that is moved up and down by an electric screw bolt, an upper limit switch that stops the pedestal at a position where the top surface of the pedestal is a predetermined distance below the cutting edge of the fixed lower blade, and the pedestal. The lower limit switch of the stand detects that the height of the stack of cut products received on the stand has reached a height that is extremely slightly lower than the cutting edge of the lower blade, and sends a detection signal to the electric screw bolt. The control unit of the electric screw bolt rotates the bolt every time it receives the above detection signal and lowers the pedestal little by little step by step until it reaches the lower limit switch. The main points are as follows.

る。That is, in the above embodiment, the carriage 5 is swung left and right based on the detection signal of the meandering detector 2 to automatically correct the meandering delivery of the web 6, and the nip roll 12 that comes into contact with the delivery roll 10.
The original fabric 6 is pulled in the right and left and lateral directions by the guide grooves 11 and 11', and the vertical wrinkles are removed at the same time by pulling the feed roll 10. The slack and horizontal wrinkles in the original fabric 6 due to the stoppage of the nine feed nine rolls 15 are eliminated by the sum of the weights of the sponge rolls 28, 28'.
The original fabric is properly adhered to the lower blade 21 of the slitter, and slitting is performed by the upper blade 27 of the slitter, and the wrinkles are removed by the guide grooves 11 and 1V of the nip roll 16 that comes into contact with the feed roll 15. Further, while the feed roll 15 is stopped, the upper cutting blade 29 descends and rises to shred the original fabric 6, and stacks the shredded cut products 47 on the pedestal 35, and the height of the stack increases. When the lower cutter blade 30 reaches a height slightly lower than the upper surface, the pedestal 35 is lowered step by step, and a predetermined number of cut products 47 can be stacked in an orderly manner and removed in a batch. This is how it was done.

有するものである。As described above, the present invention includes a cutting device blade section with a movable upper blade and a fixed lower blade that shred the original fabric during stoppage during intermittent feeding, and a blade part of the cutting device formed at the front position of the fixed lower blade for recovering cut products. space and
In the same space, there is a pedestal with a stopper for abutting the finished cut product, which is moved up and down by an electric screw bolt, and the pedestal is stopped at a position where the top surface of the pedestal is 9 predetermined distances below the cutting edge of the fixed lower blade. The upper limit switch and the lower limit switch of the pedestal detect that the height of the stack of cut products received on the pedestal has reached a height that is extremely slightly lower than the cutting edge of the lower blade, and a detection signal is generated. This is a detection device that sends a signal to the control section of the electric screw bolt.The control section of the electric screw bolt rotates the bolt every time it receives the above detection signal, until the pedestal reaches the lower limit switch. The feature is that the product is lowered in small steps, so that each time a predetermined number of cut products cut into pieces by the upper cutting blade are accumulated on the holder, the holder is lowered in small steps. In other words, the cut products are always discharged and stacked on the pedestal with a small head difference, and this stacking is done in an orderly and heavy state, and the cut products are stacked with the angle of the cut products bent. Not only does it have excellent effects, but it also has the advantage of being able to collect a large number of finished cut products that are stacked higher than the length of the finished cut products at once, which is not practical.
