Abstract: An automatic bending machine produces a steel rule punching die to be used for forming predetermined notch lines or fold lines in a paper strip, a sheet, a board member, or the like in production of a paper container or a corrugated box. The automatic bending machine has a bending tool which bends a band blade into a predetermined shape. In the machine, a diamond grinder which is laterally and vertically moved by a computer control is disposed in front of the bending tool. When the bending tool is combined with the diamond grinder, bending of the band blade, linear cutting of the both ends, nicking of a blade edge, bridging (notching) of a blade bottom, and broaching (slotting) of a blade side wall are enabled.

Abstract: An automatic bending machine is provided for automatically bending a strip blade material, wherein the automatic bending machine intermittently feeds the strip blade material through a nozzle until the strip blade material is jutted out from a nozzle gate at the end of the nozzle, and causes a CW-direction bending tool or a CCW-direction bending tool to be turned in a clockwise direction or a counterclockwise direction, respectively, to strike the strip blade material for bending it. The CW-direction bending tool and the CCW-direction bending tool are provided with a bending tool support extending at right angles thereto and a ring having a concentric hole, at the top and bottom of the CW-direction bending tool and the CCW-direction bending tool, respectively, and a shaft penetrating through the rings of the CW-direction bending tool and the CCW-direction bending tool that are superposed one upon another.

Abstract: A setup method for preventing a “two-leaf cutting” by only operating a machine without using fingers in cutting an end of a strip blade material having an enclosed rectangular geometry. The steps include: the strip blade material being once advanced to a position, where “two-leaf cutting” will not occur; then a cutting tool being lowered; a cutting tool tip of a cutting tool component being lowered to a level of the same as or under that of a top edge of the strip blade material; then the strip blade material being retracted; and finally, the strip blade material being retracted by the same amount as that of the advance from the desired position.

Abstract: An automatic bending machine produces a steel rule punching die to be used for forming predetermined notch lines or fold lines in a paper strip, a sheet, a board member, or the like in production of a paper container or a corrugated box. The automatic bending machine has a bending tool 1 which bends a band blade 12 into a predetermined shape. In the machine, a diamond grinder 20 which is laterally and vertically moved by a computer control is disposed in front of the bending tool 1. When the bending tool is combined with the diamond grinder, bending of the band blade, linear cutting of the both ends, nicking of a blade edge, bridging (notching) of a blade bottom, and broaching (slotting) of a blade side wall are enabled.

Abstract: The most important purpose of the present invention is to provide a sturdy and highly accurate bending tool which is capable of bending as deeply as over 90 deg with no need for using a mechanism, such as an extra motor, cylinder, or the like.

Abstract: A setup method for preventing a “two-leaf cutting” by only operating the machine without using fingers in cutting the end of a strip blade material 5 having an enclosed rectangular geometry using the apparatus as defined in claim 6, comprising the steps of: the strip blade material 5 being once advanced to a position, as shown in FIG. 13-C, where “two-leaf cutting” will not occur; then the cutting tool 6 being lowered; the cutting tool tip 65 of the cutting tool component 651 being lowered to a level of the same as or under that of the top edge of the strip blade material 5; then the strip blade material 5 being retracted; and finally, the strip blade material 5 being retracted by the same amount as that of the advance from the desired position.

Abstract: A lower plywood sheet and an upper plywood sheet which are set on a cylinder are cut in two processes by use of a router to create a 1.4-mm-wide groove in the back of the lower plywood sheet and in the front of the upper plywood sheet. Thus, a rotary cutting die which allows a 4-point (1.4-mm-thick) blade to be accurately inserted thereinto, a method for manufacturing the same, and a device for manufacturing the same are provided.

Abstract: A lower plywood 2 and an upper plywood 3 which are set on a cylinder 1 are cut in two processes by use of a router to create a 1.4-mm-wide groove in the back of the lower plywood 2 and in the front of the upper plywood 3, thus a rotary cutting die which allows a 4-point (1.4-mm-thick) blade to be accurately inserted thereinto, a method for manufacturing the same, and a device for manufacturing the same are provided.

Abstract: A stripping device for die cutting machine comprising a female die 2 which has female holes 21 corresponding to a plurality of external wastes 111 or internal wastes 112 on the same straight line; a male die 3 which has male pins 31 corresponding to the female holes 21; and a lower plate receiving member 43 for housing a catching plate 411 having pin catching projections 412 corresponding to the male pins 31, and cutouts 413 corresponding to a product 1 or a product bridge 1A, the lower plate receiving member 43 having spring housing holes 415 for housing springs 4153 to vertically move the catching plate 411.

Abstract: A pallet used to transport and store articles is formed by using plywood laminates or particle boards, offering a pallet which can easily be disposed of as waste when it is discarded after completion of its use as a pallet. As a pallet, is highly strong in service, and can be easily assembled by the user, being manufactured at low cost. The pallet built by combining a support 2 having a plate-like support body 25 having a support end 23 at its top and a support projection 21 on the support end 23 with a top deck 10 having a deck hole 22 corresponding to the said support projection 21. With this composition, the pallet can be easily disposed of as waste when discarding it after completion of its use as a pallet, and as a pallet itself it is very strong in service, and can easily be assembled by the user and manufactured at low cost.
