Title:
SLIT BAND PLATE MEANDERING PREVENTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/034204
Kind Code:
A1
Abstract:
Provided is a slit band plate meandering preventing device capable of stabilizing slit band plates on the center side of a conveying line. The slit band plate meandering preventing device passes, by a pinch roller, slit band plates (S1, S2) formed by slitting one strip of band plate (S) extending over the full width into two strips in a conveying line. The pinch roller includes: a lower roller (12) for supporting the lower surfaces of the slit band plates; and an upper roller (11) touching the upper surface of the slit band plates and allowing the slit band plates to approach the center line side by an outside partial depression or an inward skew angle. The device is also provided with an edge guide (1) that is positioned within a nip held between the upper and lower rollers of the pinch roller and/or in the vicinity of the nip and is used for guiding the center line edges of the slit band plates. In background technology, it has been impossible to stabilize slit band plates on the center side of a conveying line, without damaging the edges of the band plates or without using a complicated control system. Furthermore, it has been difficult to stably pass the plates during a non-steady plate passage, such as when passing the tail ends of the plates after being cut.
