ブ穿孔装置。 In a web perforating device, the web is intermittently transferred to a perforating section consisting of a punch and a die, and while the web is stopped, the punch and die engage to perforate the web. A web guide means which is curved to form a trough-like shape, a perforation portion formed such that the engaging surfaces of the punch and the die match the curved surface of the trough-like web, and a web perforated by the perforation portion remains in a trough-like shape. A web punching device comprising a web transport means for intermittent transport, and a web guide means for gradually correcting the web surface to a flat surface as the trough-like web advances, in this order.
