Apparatus for changing the traveling direction of a web-like material |
摘要 |
An apparatus for changing the direction of travel of a web-like material without inverting the front and rear surfaces of the web-like material is improved in that a plurality of guide rotors are disposed on each of a plurality of spiral curves along an imaginary conical surface so as to be rotatable about axes intersecting at right angles with the corresponding spiral curve on the imaginary conical surface, and a conical surface formed by an enveloping surface of these guide rotors is used as a traveling path of the web-like material, whereby shortcomings inherent in such apparatus in the prior art can be eliminated.
