Abstract
A rolling stand includes a roller-carrier substantially in the form of a ring-shaped body having the rollers journalled on its interior; the roller-carrier is slidable along a longitudinal rolling axis L between an operative position occupied during the rolling process, where it is locked inside an outer structure of the rolling stand, and a non-operative position where it is removed from the structure. Provided within the rolling stand are guide means for guiding the roller-carrier movement along the axis L and means of locking the roller-carrier in the operative position.
Claims14
A rolling stand, having a longitudinal rolling axis, comprising:
- at least three driven rollers;
- an outer support structure for said rollers;
- driving means and associated transmission means for driving said rollers;
- a roller-carrier substantially in the form of a cylindrical body, wherein said rollers are each supported rotatable about a respective rotation axis via supporting means and carrier means provided in said roller-carrier for supporting each of said rollers in a pivotable manner;
- said roller-carrier being slidably supported within said outer support structure such that the roller-carrier is slidable along said longitudinal rolling axis between an operative position locked within said outer support structure and a nonoperative position removed from said outer support structure via sliding means and locking means provided in the rolling stand;
- at least one adjuster device for each roller, each adjuster device being operative to set a distance between said rotation axis of a respective roller and said longitudinal rolling axis, each adjuster device comprising a stationary part rigidly connected to said outer structure and a moving part reciprocable along a radial direction relative to said longitudinal rolling axis, said moving operating on said supporting means of the respective roller, and said carrier means holding said supporting means pressed against said moving part of each adjuster device.
