Abstract
A roller guide (1) for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock. The roller guide comprises a frame arrangement (2), a pair of guide rollers (3, 4) configured to, in a closed position, engage opposite surface portions of the stock,and positioning means for adjusting a lateral distance between the guide rollers. The roller guide further comprises detection means (13) configured to detect a longitudinal position of a piece of stock (20) with respect to the guide rollers. The positioning means is configured to adjust the lateral distance between the guide rollers in response to said detection.

A roller guide (1) for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock, the roller guide (1) comprising:
- a frame arrangement (2),
- a pair of guide rollers (3, 4) mounted on the frame arrangement (2), which guide rollers are configured to, in a closed position, engage opposite surface portions of the stock, the guide rollers (3, 4) being rotatable about parallel axes of rotation (C3, C4) perpendicular to the longitudinal feeding direction (A), and
- positioning means for adjusting a lateral distance between the guide rollers (3, 4), wherein
- the roller guide further comprises detection means (13) configured to detect a longitudinal position of a piece of stock (20) with respect to the guide rollers (3, 4), and that the positioning means is configured to adjust the lateral distance between the guide rollers (3, 4) in response to said detection.
A method for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock, wherein a roller guide (1) is used, the roller guide (1) comprising:
- a frame arrangement (2),
- a pair of guide rollers (3, 4) mounted on the frame arrangement (2), which guide rollers (3, 4) are configured to, in a closed position, engage opposite surface portions of the stock, the guide rollers (3, 4) being rotatable about parallel axes of rotation (C3, C4) perpendicular to the longitudinal feeding direction (A), wherein the method comprises the steps:
- detecting a longitudinal position of a piece of stock (20) with respect to the guide rollers (3, 4), and
- in response to said detection, adjusting a lateral distance between the guide rollers (3, 4).
