Abstract
A device for use in conjunction with a slice lip adjusting mechanism for controlling the distribution of stock across the web of a paper machine to obtain a desired cross-machine profile of basis weight, moisture, caliper and the like.

An apertured adjusting arm engages the slice lip for fine adjustment of the lip position. Disengagement between the adjusting arm and the slice lip is prevented by a headed bolt which passes through the aperture in the adjusting arm and is received in threaded engagement in the slice body, in combination with a plug which is received in threaded engagement at the head of the bolt and a compressed spring which acts between the plug and the adjusting arm. A tube is provided with an internally threaded portion receiving the plug in threaded engagement at one end, with the opposite end of the tube being spaced from the adjusting arm by a small predetermined clearance thereby limiting the extent to which the adjusting arm can move away from engagement with the slice lip. Locking means are provided to lock the tube in …
