Claim:
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.
