ABSTRACT:
A strip-covered roll and the method for manufacturing the same, according to which the roll includes an inner roll body and a plurality of circumferential strip portions surrounding and engaging the inner roll body so as to cover the latter, these circumferential strip portions also engaging each other and being distributed axially along the inner roll body. Each circumferential strip portion has on one side a circumferential groove and on the other side an integral circumferential projection, and the projection of one circumferential strip portion is received in and fills the groove of the next circumferential strip portion, the groove having in its interior a greater transverse dimension than at the side surface of each circumferential strip portion which is formed with the groove, so that in this way the circumferential strip portions are locked to each other. According to the method, the circumferential projection of each circumferential strip portion is initially of a configuration enabling it to enter into the groove of the next circumferential strip portion, and when these strip portions are pressed against each other the circumferential projection is deformed so as to fill the groove and provide the interlock.
