Device at machines for continuous separation of a strip from a hose-formed material web

A device for continuously separating at least one strip from a material web in hose form, the device comprising:

• at least two lead rollers extending generally in the same direction and being generally next to each other, a first one of the rollers being tiltable relative to a second one of the rollers, at least one of the first and second rollers being rotatable as the web is fed past the rollers, and a severing device generally supported near the rollers for severing the web;
• an axially displaceable rod supported at the device and axially displaceable with respect to the second roller, and means located between the first tiltable roller and the second roller for halting the axial displacement of the rod;
• the tiltable first roller being supported on the axially displaceable rod for being displaced axially with the axially displaceable rod;
• a shaft supported on and extending parallel to the axially displaceable rod, the first roller being supported on the shaft on the rod for being pivotable about the shaft around a first axis defined by the shaft;
• first means on the rod for arresting motion of the first roller on the rod in different angular positions around the first axis at the shaft;
• a second axis on the axially displaceable rod generally perpendicular to the rod, the first roller being positioned at a distance along the length of the rod from the second axis, whereby the first roller may be pivoted around the second axis to different tilt orientations;
• second means for arresting motion of the first roller around the second axis;
• a retainer for the rod spaced away from both the tiltable first lead roller and from the second axis, the retainer being pivotable about a third axis perpendicular to the first and second axes, and such pivoting around the third axis being in a displacement plane defined by movement of the rod about the third axis whereby the rod may be pivoted to different angular positions around the third axis for swinging the first lead roller around the third axis;
• and a third means for arresting the rod in a selected position around the third axis.
