Title: Curling tendency correcting device
Inventor: KAMATA KENJI
IPC: B65H23/28
Filed: 1984-11-20
Abstract: PURPOSE:To prevent reverse curling due to overcured curling by properly using curling-curing rollers of different diameters depending on the degree of curling in a curling tendency curing device for a roll of paper, etc. CONSTITUTION:When curling tendency is low, a roll of paper 1 which is fed from an inlet side feed roller 2, undergoes curing for curling by a larger- diameter curing roller 5A, and then, is discharged through a conveying passage 7A. When the curing tendency is high, a solenoid 9 which is interlocked with a detector for the amount of curling, operates causing a changeover leaf spring 13 to rotate counterclockwise centering around a fulcrum 11. due to this changeover, the roll of paper 1 which is originally being curled in the downward direction, will advance straight and undergoes curing for curling by means of a small-diameter roller 5B, and then, is discharged through a conveying passage 7B.

Title: Slide punch moving device of press molding
Inventor: KIMURA NOBUHIRO
IPC: B21D5/01
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To make a smooth movement of a slide punch possible by mounting a slide cam, having an inclined slide plane and a subsequent vertical plane, at an above end of a position holding part which connects with a roller, to the upper die set and by installing an activating part and a stopper to the bottom die set. SOLUTION: When the upper die set 13 descends, the position holding part of the slide cam 14 descends. Resulting from this movement, the roller 8 rotates but the slide punch dose not move. When the upper die set 13 descends, a slide plane 16 engages with the roller 8, which slides its position towards the molding side while rotating by the inclination of the sliding plane 16. Thereby, the slide punch 1 moves forward and stops at a position where the vertical plane of the slide cam 14 engages with the roller 8. A coil spring 11 is compressed and obtains an enerdization force for getting back to its original position. When the upper die set 13 descends furthermore, the slide punch 1 keeps its forward position as is, and a holder presser 18 and a punch presser 19 press and fix a member on the upper faces of the holder 3 and the slide punch 1.
