Abstract A puller for extrusion profiles at an extruder comprises a carriage which is movable on rails along a runout con- veyor for the extrusion profiles and at which a puller head with a fixed and a movable clamping jaw is arranged for pivoting movement about a vertical axis so that the puller head may be swung laterally out of the runout conveyor. The two clamping jaws extend approximately across the width of the runout conveyor, and the movable clamping jaw comprises a plurality of clamping segments which are supported at the puller head for free swinging movement about a horizontal axis and adapted to be pivoted in opening sense by a drive means. The clamping segments are provided with clamping curves of such curvature that, at all pivot positions of the clamping segments,the points of contact between the extrusion profile to be clamped and the clamping curve always lie at least approximately on a clamping straight line intersecting the horizontal pivot axis at an inclination of a desired clamping angle with respect to a line perpendicular to the runout conveyor.
