Claims15
A folder, comprising:
- at least two folding cylinders having cooperating folding members in the form of folding blades and folding jaws, at least one of said folding cylinders being provided with circumferential sections;
- and,
- setting means for adjusting said circumferential sections in a radial direction wherein said circumferential sections are arranged and tiltable about an axis parallel to the cylinder axis provided in an area of a leading end of said circumferential sections and with a tailing end of said circumferential sections being extendable in a radial direction by means of said setting means.
A folder, comprising:
- at least two folding cylinders having cooperating folding members in the form of folding blades and folding jaws, at least one of said folding cylinders being provided with adjustable circumferential sections trailing the folding members and between successive folding members, said adjustable circumferential sections being formed by spaced rails with sai spaced rails being arranged adjacent one another with spacings therebetween and jointly projectable in a radial direction and, further, with fixed strips extending said rails and forming non-adjustable circumferential sections;
- and,
- setting means for adjusting said adjustable circumferential sections in a radial direction wherein said adjustable circumferential sections are arranged and tiltable about an axis parallel to the cylinder axis provided in an area of a leading end of said adjustable circumferential sections and with a tailing end of said adjustable circumferential sections being extendable in a radial direction by means of said setting means.
