Forming apparatus using a pair of rollers

Abstract

The forming apparatus including: at least one forming roller; a roller shaft, on which the forming roller is attached; a pair of mutually spaced apart bearing stands, on each of which the roller shaft is rotatably and axially supported; a first coupling arranged on the roller shaft to serve as an axial positioning of the forming roller; and a second coupling releasably coupled to the first coupling, the roller shaft being divided into a first shaft (8A) rotatably and axially supported on one of the pair of bearing stands and a second shaft rotatably and axially supported on the other of the pair of bearing stands, both the first coupling and the forming roller being removably attached on the divided end of the first shaft, the second coupling being fixedly attached onto a divided end of the second shaft, and the second shaft being further slidably supported on the other of the pair of bearing stands by a slide stroke by which a spatial interval from the divided end of the second shaft to the divided end of the first shaft is enabled to be secured to allow removing and attaching operations for at least the first coupling and the forming roller.
