<p>PCT No. PCT/SE88/00346 Sec. 371 Date Dec. 21, 1989 Sec. 102(e) Date Dec. 21, 1989 PCT Filed Jun. 22, 1988 PCT Pub. No. WO88/10181 PCT Pub. Date Dec. 29, 1988.A device at machines for continuous separation of at least one strip (49) from a hose-formed material web (14). The device (19) incorporates at least two lead rollers (16, 18) at least one (18) of which being tiltable relative to the other, thus that the end portion of the material web, which is thread on the guide rollers at rotation of the guide rollers, is imparted a continuous, axial feeding motion towards a severing device (50). The tiltable lead roller (18) is supported at one free end of an axially displaceable and in different displacement positions arrestable rod (20), the free end of which is pivotably to a limited extent on one hand about a shaft (31) mainly parallel with the rod and on the other hand about an axis (44) mainly perpendicular to the rod. This (20) is equipped with means (33, 43) for arresting its free end in different angular positions.</p> |
