PROBLEM TO BE SOLVED: To position a metal mold with high accuracy even during processing at a high speed in a rotary die device.SOLUTION: A rotary die device 1 comprises: chains 17 and 19 on which metal molds 23 and 31 are loaded and which are wound around driving and following sprockets 13 and circularly moved; a cam follower 37 which is so located as to project a front end part and a rear end part of width direction both side faces of mounting plates 21 and 29 for the chains 17 and 19 to the metal molds 23 and 31 in a width direction; and routes 40 which are so located as to respectively face width direction both sides of the chains 17 and 19 and are provided along a movement locus of the cam follower 37. The device further comprises a guide plate 39 which suppresses oscillation of the metal molds 17 and 19 in a direction orthogonal to the chains 17 and 19 by bringing the cam follower 37 into engagement with the routes 40.SELECTED DRAWING: Figure 14D |
