Method, control, and apparatus for taking up a billet produced in an extrusion or tube-making press includes applying a controlled pull-away tractive force, which keeps the emerging billet straight and does not affect the formation of the billet, increasing the pull-away tractive force in proportion to the extruded billet length, unit length weight and coefficient of friction between the billet and the delivery table, superimposing the pull-away tractive force upon the take-up tractive force determined from the cross-section and flow behavior in the die. After a billet has been separated and withdrawn from the die, the pull-away force and the length of the emerging billet are measured and the pull-away force, divided by the billet length, is entered as a set value for the specific profile frictional force to be multiplied by the billet length, which is determined by a path measurement, when extruding a subsequent billet of the same nominal cross section. The control is carried out such that, in addition to a value, which takes account of the resistance to motion of the carriage of the take-up device, as a first addend, and in addition to a base value--dependent upon the billet cross-section--of the take-up force as a second addend, starting from the point at which the billet tip is gripped by the grippers of the take-up device, an increasing value, which is the respective product of the result of a continuous delivery path measurement and a predetermined specific profile frictional force between the emerging billet and the delivery table, is determined and entered as a third addend as a desired value of the tractive force exerted on the billet tip.

An apparatus for pulling extrusions from a press, comprising two pullers (5,6) which alternatingly pull the extruded product (3) along an extrusion path and each are equipped with a separator (16) that moves along, and further comprising a cross-transfer conveyor (8) which conveys the extruded products upon separation in a direction transversely of the extrusion direction (F) for further processing, is characterized in that puller heads of the pullers (5,6) are designed to be movable transversely out of the extrusion path (2) for lateral shifting of the clamped extruded product by a cross-drive.

A method and apparatus for removing an extruded profile shape from an extrusion press efficiently and economically during an extrusion operation. A first and second extrusion puller are mounted on suitable guide for movement along an extrusion line. One of the extrusion pullers receives and grips a profile shape as it is extruded from an extrusion press, and this puller exerts a pulling force on the profile shape. The first puller can pass off the profile shape to the second puller as the profile shape is extruded, thereafter the second puller would grip and pull the profile shape and the first puller would release its grip. When it is desired, or necessary to remove the profile shape from the extrusion press, the puller which is not gripping the shape grips the profile shape and a shear within the press shears off a butt portion of the billet. Then, both pullers, in tandem, apply a pulling force on the profile shape away from the extrusion press. The profile shape is stripped from the die. Thereafter, the first puller releases its grip and returns to receive another profile shape while the second puller moves the profile shape to further conditioning operations. Finally, the second puller returns to its home position and waits to receive the next extruded profile shape.
