Abstract

A paper forming device of a paper machine enables a change-over between a thin paper high velocity forming and a thick paper forming. In the paper forming device, stock liquor S is discharged from a headbox 1 onto a wire 2 and, while being transferred on the wire 2, is dewatered by a dewatering equipment and further by a suction box 6. A forming roll 13, wound with an extended felt 7, is arranged movably up and down above the wire 2 near the headbox 1. When a thin paper is to be formed, the forming roll 13 is moved down so that a nip of the stock liquor is formed between the wire 2 and the felt 7. Thereby, the stock liquor S discharged from the headbox 1, can be comparatively immediately nipped between the wire 2 and the felt 7.
