1. A method of forming an irregularly shaped, elongated product piece of a partially elastic material, the method comprising:
pressing the product piece
in a longitudinal direction and
in at least one transverse direction relative to the longitudinal direction
in a forming tube to form a product caliber which has a cross-section which is largely uniform over its length,
wherein
before the pressing of the product piece
its weight as well as its length in a feed direction are determined,
from the weight and the length, an average cross-section of the product piece in an unpressed state is determined,
the product piece is inserted into the forming tube,
then an inner free cross-section of the forming tube is set to a value that corresponds to the average cross-section.
