Abstract: In a paper machine having a roll (12) rotating about an axis (A1) extending in a cross machine direction, and having a doctor blade (14) applied to the roll surface by a blade holder (16) parallel to the axis and carried on a doctor back (18), an apparatus is provided for accommodating relative movement between the blade holder (16) and the doctor back (18) in the cross machine direction during mounting and removal of the blade holder (16). The apparatus comprises a rail (42) fixed to the doctor back (18) and extending longitudinally in the cross machine direction. A groove (46) extends along the length of the guide rail. The groove (46) has a bottom (48), a width measured between confronting sides (50), and a top defined by ledges (52) projecting inwardly from the sides (50), with inner edges spaced one from the other to define a slot (54) that underlies the blade holder and has a width narrower than the width of the groove (46). A plurality of shafts (56) are spaced along the length of the blade holder and project downwardly through the slot (54) and into the groove (46). First (62) and second (64) independently rotatable elements are carried by each of the shafts. The first rotatable elements (62) are located in the slot (54) and are dimensioned to contact the inner edges of the ledges (52), and the second rotatable elements (64) are located in the groove (46) and are dimensioned to contact the undersides of the ledges (52).

Abstract: A reciprocating doctor (12) is provided for doctoring the cylindrical surface (20) of a roll (10) rotating about a first axis (Al). The doctor includes a doctor back (14) with a blade holder (20) carrying a doctor blade (18). The doctor back has journals (16) aligned on a second axis (A2) parallel to the first rotational axis of the roll. The journals are rotatably supported in sleeve bearings (26), and the sleeve bearings are in turn supported by diaphragms (30) spaced along the second axis. The sleeve bearings are fixed axially on their respective, journals, and the diaphragms have hub portions (34) surrounding and fixed relative to the sleeve bearings, and peripheral portions (38) surrounding the hub portions and fixed relative to a support structure (24). The diaphragms are configured to resiliently accommodate reciprocating movement of their hub portions and associated sleeve bearings relative to their peripheral portions and associated support structure. A first operating mechanism (70, 72) serves to rotate the doctor back about the second axis, and a second operating mechanism (74) serves to impart reciprocating movement to the journals and their sleeve bearings along the second axis.
