Abstract: A spreader roll has at least two partial rolls (10, 20, 30) with a composite shell (11, 21, 31) and two end part rolls (10, 30) connected together directly or by an intermediate part roll (20) so a gap (D) remains between the end surfaces of the shells (11, 21, 31) of the partial rolls (10, 20, 30). An end journal (12, 32) is connected to the outer end of the roll shell (11, 31) of each end part roll (10, 30). Each end journal is supported to frame constructions (R) by an end bearing (40, 50). The partial rolls (10, 20, 30) are connected by an intermediate journal (13, 33) rotating with the roll shells (11, 21, 31) of the partial rolls (10, 20, 30). The intermediate journal (13, 33) is supported to a fixed support beam (P) external to the spreader roll by an intermediate bearing (60, 70).

Abstract: A composite doctor arrangement for a web forming machine or web handling machine has a beam structure (10) with a mounting piece (13) fitted to it. A blade holder (11) is fitted to the mounting piece, with a blade (12) fitted to the blade holder (11). The mounting piece (13) is fitted axially and movably in the beam structure (10) by a form-locked mounting counterpiece (14), where the form locking is arranged so that it is fixed in the lateral direction of the blade (12) and essentially free in the longitudinal direction of the blade (12).
