Title: Paper folding device
Inventor: DOBASHI KENJI
IPC: B65H45/107
Filed: 1992-04-23
Abstract: PURPOSE:To prevent the generation of a slip between a pair of folding rollers at the normal/reverse rotation change-over time of the folding roller pair so as to prevent the double-folding of sheets and improve folding accuracy. CONSTITUTION:In association with the repetition of normal/reverse rotation of a first folding roller pair 22 and a second folding roller pair 23, a sheet guide member 25 is oscillated laterally. A sheet 24 is thereby fed in between the respective rollers of the first folding roller pair 22 or second folding roller pair 23 so as to be folded only the desired number of times. A slip preventing roller pair 30 comes in rotational contact with the first folding roller pair 22, and a slip preventing roller pair 31 comes in rotational contact with the second folding roller pair 23. The first folding roller pair 22 and second folding roller pair 23 are prevented from slipping at the change-over time of normal/reverse rotation by these slip preventing roller pairs 30, 31.
