Abstract:
A device for processing ply material including paper, said ply material defining a layer plane, a center plane oriented at right angles with respect to the layer plane and a length direction, comprising:a stationary device base;first and second transverse slides simultaneously displaceable in first and second contour directions on said device base, said second contour direction opposing said first contour direction and said contour directions oriented transverse to said length direction and parallel to said layer plane;first and second working units, each of said working units including respective first and second tool units in an operating state, from opposing sides of the ply material said first and second tool units simultaneously processingly engaging the ply material at first and second working points, said tool units defining first and second working planes oriented transverse to the ply material and transverse to said first and second contour directions, said first working unit being pivotably mounted on said first transverse slide about a first contour axis through said first working point and oriented transverse to said layer plane, said second working unit being pivotably mounted on said second transverse slide about a second contour axis through said second working point and oriented transverse to said layer plane; and,control means for commonly positionally varying said first and second working units with respect to said device base while in said operating state, said control means including:a driving member for driving said first and second transverse slides respectively in simultaneous and opposing first and second transverse motions, said first transverse motion being in said first contour direction and said second transverse motion being in said second contour direction,a setting motor for uni-directionally driving said driving member and simultaneously counter-directionally displacing both said first and second transverse slides, anda pivot motor means for simultaneously counter-directionally pivoting said first working unit about said first contour axis and said second working unit about said second contour axis, the center plane being located between said first and second contour axes.
