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).
