One-sided corrugated cardboard machine comprising a first fluted roller and a second fluted roller in meshing engagement with each other and between which a web of cardboard is introduced to be corrugated, the second fluted roller being provided in the circumferential outer surface thereof with several annular grooves arranged at axially spaced intervals, and a device which during the movement of the web of corrugated cardboard from the position of engagement between the second fluted roller and the first fluted roller to the position of engagement between the second fluted roller and an auxiliary roller biases the web of corrugated cardboard with a vacuum pressure via the suction grooves, wherein the second fluted roller has suction boxes associated therewith one each at the inlet and the outlet of the web of cardboard, said suction boxes respectively extending only over a small portion of the circumferential region of the fluted roller not covered by the web of corrugated cardboard and being closed on the side facing the fluted roller except for small openings in the region of the suction grooves, and wherein on the sides of the suction boxes facing each other sealing elements are respectively engaging within the suction grooves.

One-sided corrugated cardboard machine

An apparatus for longitudinally cutting and grooving a continuously moving length of material. The device has at least two cutting and grooving units, each provided with separate cutting and grooving tools. The units are positioned at different vertical levels and are vertically movable in unison in the same direction to selectively place one of the units in position for operating and the other unit in position for adjustment.

Machine for longitudinally cutting and grooving a length of material,

A heating device for corrugated cardboard in a corrugated cardboard pasting machine, comprising several heating plates spaced in feeding direction and covering the maximum width of the corrugated cardboard strip while being adapted to be connected to a source of heat via a control device and against the upward facing heating surface of which the cardboard is guided under load by a weighting belt and/or compressed air, with two or more separate heating plates arranged side by side transversely of the direction of movement of the corrugated cardboard in at least one section and adapted to be separately heated by means of the control device.
