    摘要: A web width adjusting device can adequately adjust the width of paper web which is travelled through at least two printing sections. The travelling web is sandwitched by a pair of contact means including a plurality of contact members which are aligned in parallel to the axis of cylinders for driving the paper web. The contact members of one alignment are alternatively in contact with the web surface with respect to the other alignment.

    摘要: A widening device for increasing the width of a moving web of material comprises a rotatable profiled roller, the outer surface of which defines a plurality of radial projections and recesses distributed along the length of the roller and first and second co-operating rollers rotatable at the same speed as the profiled roller. The first and second co-operating rollers define projections and recesses complementary to those of profiled roller and define first and second treatment nips which serve to increase the width of a web of material passed therethrough. The projections on the co-operating roller defining the second treatment nip extend more deeply into the recesses of the profiled roller than do the projections on the co-operating roller which defines the first treatment nip so that the web of material is stretched gradually over two stages with the stretching effect being uniform across the entire width of the web.

    摘要: An apparatus for displacing a continuous flat sheet of material having a first edge and a second edge, running along a first plane in a first direction which is the direction of its centerline to a parallel but sideways displaced direction in a second plane the direction being parallel to the first, in which the second edge of the sheet is displaced from the first plane to decrease the path length in the first plane of the second edge relative to the first edge to produce a first change in direction of running and subsequently to displace the first edge from the second plane to decrease the path length in the second plane of the first edge relative to the second edge to similarly produce a second change in direction of running equal in magnitude but in an opposite direction to the first change in direction so that the final direction of running is parallel to the first direction of running.
