Patent ID: 7776183

Claim:
A forming section for a gap blade former type papermaking machine, the forming section having a machine direction and comprising: a. a headbox which delivers a jet of papermaking stock; b. a lead-in roll located immediately downstream of the headbox; c. a conveying forming fabric and a backing forming fabric, each mounted for advancing movement in the machine direction and having facing advancing sides between which an embryonic paper web is formed; d. an impingement shoe over which the conveying forming fabric moves in sliding contact and the jet of papermaking stock is delivered onto the conveying fabric at a point of impingement located over the impingement shoe; e. a forming shoe, located immediately downstream of the impingement shoe, over which the backing forming fabric slides; the impingement shoe is mounted with an adjustment mechanism for linear movement in the machine direction or a combination of pivoting and the linear movement, from a fixed first position to one of a plurality of fixed second positions so that a position of the point of impingement of the jet of papermaking stock on the conveying fabric in an area of sliding contact over the impingement shoe is adjusted by linear movement of the impingement shoe in the machine direction or by a combination of rotating the impingement shoe about a first pivot point and the linear movement of the impingement shoe.
