Document Type and Number:
Japanese Patent JP3936913
Kind Code:
B2
Abstract:
In a paper machine having a roll rotating about an axis extending in a cross machine direction, and having a doctor blade applied to the roll surface by a blade holder parallel to the axis and carried on a doctor back, an apparatus is provided for accommodating relative movement between the blade holder and the doctor back in the cross machine direction during mounting and removal of the blade holder. The apparatus comprises a rail fixed to the doctor back and extending longitudinally in the cross machine direction. A groove extends along the length of the guide rail. The groove has a bottom, a width measured between confronting sides, and a top defined by ledges projecting inwardly from the sides, with inner edges spaced one from the other to define a slot that underlies the blade holder and has a width narrower than the width of the groove. A plurality of shafts are spaced along the length of the blade holder and project downwardly through the slot and into the groove. First and second independently rotatable elements are carried by each of the shafts. The first rotatable elements are located in the slot and are dimensioned to contact the inner edges of the ledges, and the second rotatable elements are located in the groove and are dimensioned to contact the undersides of the ledges.
