Abstract
An apparatus for picking up an auxiliary pile during a renewal of a main sheet pile when feeding sheets to a printing machine. The apparatus has loadbearing elements arranged on a holder for the auxiliary pile, and a positioning device for the loadbearing elements under the auxiliary pile. The loadbearing elements are flexible with respect to positioning forces acting from outside.
Claims3
An apparatus for picking up an auxiliary pile during renewal of a main pile when feeding sheets to a printing machine, comprising:
- a holder for holding the auxiliary pile;
- said holder including loadbearing elements to be placed underneath the auxiliary pile;
- said loadbearing elements being flexible elements configured to yield to externally acting positioning forces;
- a guide disposed on said holder, for a horizontal compensating movement of said loadbearing elements;
- a second guide mounted to said holder, for a vertical compensating movement of said loadbearing elements;
- said holder including a loadbearing rail, a two-armed lever carrying rollers at free ends thereof, and said holder being formed with two mutually parallel surfaces extending perpendicularly to a direction defined by said guide;
- and
- a sprung element disposed for biasing said holder in a horizontal preferred position when the positioning forces do not act on the apparatus, said sprung element being a compression spring which, in the preferred position, bears against said loadbearing rail and said two-armed roller lever, with said rollers bearing against said two surfaces formed on said holder.
