とし、製造速度の高速化も図り難い問題があつ
た。 The applicant previously proposed a device for continuously supplying such accumulated pieces from a wide continuous paper (Japanese Patent Laid-Open No. 55
-5364 Publication). This device forms multiple sets of stacked pieces, one row at a time, by sequentially cutting multiple stacked sheets of roll paper at predetermined intervals in the vertical and horizontal directions. Since each set of stacked pieces is formed directly from paper, it is unavoidable that chips are generated at both ends in the width direction.Furthermore, a complicated device is required to separate and feed the cut stacked pieces, which slows down the production speed. There was also the problem that it was difficult to increase the speed.

本発明は上記問題を一挙に解消したものであつ

とは勿論である。 The drawing shows an example in which three paper strips are polymerized to form a napkin, emphasizing the thickness, but the number of stacked paper strips can be increased to four or more, and the number of stacked paper strips can be increased to four or more. Of course, the material can be changed as appropriate, such as cloth or synthetic resin sheet, depending on the object to be formed.

る。 The presser conveyor 6 has an inverted Y-shaped mounting plate 61 whose approximate center is pivoted to the tip of the swinging plate 41 and its upper end is pivoted to the tip of the swinging rod 42, and pulleys 62 are mounted at the center and both lower ends of the mounting plate 61. , 63, 64 are arranged in a triangular shape, and a belt 65 is attached surrounding each pulley 62, 63, 64. The presser conveyor 6 has an open portion 34 of the lower conveyor 32 on its lower surface.
It constitutes a holding surface 66 that is slightly shorter and parallel to the conveying surface. Furthermore, the upper pulley 62 is connected via an endless belt to a pulley 67 provided on the fulcrum 43 of the swing plate 41, and the rotation of the pulley 67 constantly moves the holding surface 66 in the same direction as the transfer conveyor 31 at the same speed. Alternatively, the presser surface 66 is moved intermittently, and therefore descends at the same time as the stacked base paper 15 is cut.
The strips 3 and 23 are transferred while being pressed on the inclined surfaces 24 and 25, and are reliably fed to the individual cutting section 7 as a series of thin strips 35 without separating the respective accumulation strips 23.

ンベア８９で次段に送られる。 In the transfer section 84, when the stacked piece 81 is transferred from the sending conveyor 82 to the receiving conveyor 83, a tensile force is applied to the front and back of the stacked piece 81 due to the difference in transfer speed between the two conveyors 82 and 83, and the connecting portion 36 of the stacked piece 81 is
Two sets of fan-shaped plates 85 and 86 are arranged above and below the transition path, and the accumulation piece 8 is placed between the circular arcs 87 and 88 of the fan-shaped plates 85 and 86.
Approximately one-third of the remaining portion is picked up and forcibly sent to the receiving conveyor 83. That is, as shown in FIG. 3a, while the first half of the stacked piece 81 passes through the delivery section 84, the stacked piece 81 is passed through as it is, and as shown in FIG. 3b, the second half of the stacked piece 81 passes through the delivery section 84. When reached, both arcuate surfaces 87, 88 of fan-shaped parts 85, 86
The stacked pieces 81 are sandwiched from above and below by the feed conveyor 82.
By shifting the arcuate surfaces 87, 88 at higher speeds, the stack 81 is fed towards the receiving conveyor 83 without any tensile forces acting on it. Therefore, even when separating the stacked pieces 81 including the connecting portions 36, the length of the stacked pieces 81 does not increase or the stacked pieces 81 disassemble, and as shown in FIG. , 81 and sent to the next stage by a conveyor 89 with claws.
