ABSTRACT:
A multi-part gripping device for pressing together flooring elements, such as laminates and finished parquet, in side-by-side relationship includes two rod parts that are axially and telescopically connected, one of said rod parts including a pressure jaw at an end having parallel shoulders that extend toward the other rod part, the shoulders being at a different spacing from the associated rod part for abutting a base portion of a flooring element over which the gripping device is positioned. A longitudinally adjustable lead screw is pivotally connected between the two rod parts for moving the two rod parts together, such that a connecting pressure is applied to a flooring element being interconnectably positioned adjacent one or more previously positioned flooring elements.
