Press clamping apparatus for use in automatic punching machine for cardboard boxes, has radial recesses, formed around radial passage of main board, which pass through radial projections around cylindrical base of guiding device

摘要

A guiding device has a cylindrical base with a flange around one end. Peripherally spaced radial projections, formed around the base, are axially spaced from the flange at a distance corresponding to the thickness of a main board (10). The main board forms a passage (12) surrounded by peripherally spaced radial recesses (14a-14d). The recesses engage and pass through the radial projections as the base is penetrated through the passage. The base is then rotated to fix the main board.
