Abstract
A die assembly (10) having a first die part (12), which includes a first lip (16) that, in combination with a second lip (18), defines a feed gap (20). The first die part (12) also includes a rear portion (22), a front portion (24), a slot (26) between these portions (22,24), and a gap-setting device (28) that is mechanically movable within the slot (26) so as to enable the movement of the front portion (24) relative to the rear portion (22). The first lip (16) is carried by the front portion (24), whereby movement of the front portion (24) in one direction moves the first lip (16) relative to the second lip (18), thereby adjusting the feed gap (20). The geometries of the slot (26) and the gap-setting device (28) are such that movement in a second opposite direction is limited to a known position, thereby providing a registration position for the front portion (24) of the first die part (12) and thereby providing a registration position for the first lip (16).
