Abstract

The invention relates to a device for deflecting sections of strip, in particular metal strip, in a coiling plant, from a beginning guide channel (1) to an end guide channel (2) and vice-versa, comprising a driver (3) with a pair of driver rollers (4, 4′) and control elements arranged downstream in strip conveyance direction, comprising a switch (5) that can be swiveled towards the beginning guide channel (1) or the end guide channel (2), and a guide table (6) which is swivelably supported under the switch (5) and positionable as a wiper against the lower driver roller (4′). The deflection of sections of strip is optimized in that the switch (5) is convexly shaped at its top and bottom sides and is flexibly arranged at the outlet end of an assigned strip transport roller-conveyor (7, 7′), such that it clears the beginning guide channel (1) when in a raised position and rests in the function of a wiper against the upper driver roller (4), and in that the guide table (6) is concavely shaped corresponding to the bottom of the switch (5). An actuating mechanism each, for example, a hydraulic unit (8, 8′), is assigned to both the switch (5) and the guide table (6).
