Abstract
Pull lays on a feed table of a sheet-fed rotary printing machine are adjusted by a pulling device for laterally aligning sheets thereon. A spindle, which extends transversely to the travel direction, displaces the pull lays for adjusting to a sheet format to be processed. The spindle engages indirectly at a housing of the side lays which is provided with bearing and guide elements. The pull lays are thereby subject to an energy storing device which supports them in a guide transversely to the feed table.
Claims18
A pull lay adjusting assembly for laterally aligning sheets on a feed table of a sheet-fed rotary printing press, comprising:
- pull lays movably disposed relative to a feed table of a printing press transversely to a travel direction of the sheets through the printing press;
- a spindle extending transversely to the travel direction for displacing said pull lays and for adjusting to a sheet format of the sheets;
- a housing of said side lays, said spindle extending parallel to said housing;
- and
- slaving means operatively associated with said spindle, said slaving means engaging said housing of said pull lays.
A pull lay adjusting assembly for laterally aligning paper sheets on a feed table of a sheet-fed rotary printing machine, comprising:
- a feed table;
- pull lays with a housing supported on said feed table and being movable transversely to a travel direction of the sheets through the sheet-fed rotary printing machine for selectively adjusting the assembly to a sheet format to be processed;
- an energy storing device disposed on said housing, said housing having bearing and guide elements, said guide elements being movably supported in guides formed in said feed table under a force influence of said energy storing device.
A pull lay adjusting assembly for laterally aligning sheets on a feed table of a sheet-fed rotary printing machine, comprising:
- a feed table;
- pull lays supported on said feed table and being movable transversely to a travel direction of the sheets through the sheet-fed rotary printing machine for selectively adjusting the assembly to a sheet format to be processed;
- a drive member supported in said feed table for transversely moving said pull lays;
- a drive shaft for introducing a pulling force on said pull lays, said drive shaft including slaving means for transmitting torques to said drive member.
A pull lay adjusting assembly for laterally aligning sheets on a feed table of a sheet-fed rotary printing machine, comprising:
- a feed table for supporting sheets to be processed, said feed table having side walls and crossbars disposed transversely to a travel direction of the sheets through the printing machine;
- pull lays movably disposed on said feed table for adjusting to a sheet format to be processed;
- said crossbars, in the region of the pull lay adjusting device, together with said side walls forming a one-piece housing.
