Abstract
Abstract An arrangement for controlling the roller gap, especialy of multi-roller systems, in which the transmitter housing is two sectional and the housing sections are arranged on both sides of the plane through the centers of the working rollers. The primary elements are designed for the direct, e.g., inductive contactfree stroke measurement to ascertain the roller gap and are so connected to the rest of the central device, i.e., the ratedactual-comparitive stage, that the mean value of the two primary elements of one frame side represents the actual value of this frame side.

Claim 3
Dependent Claim
90 words
An arrangement according to claim 1, in which the first and second journaling means are split so as to form a substantially horizontal gap each, and in which each of said first and second journaling means includes an outer bearing cup, each of said outer bearing cups having its front portions when viewing in the direction of rotation of said roller pivots linked to the respective adjacent transmitter housing means and having its rear portion against spring thrust connected to the rear portion of the respective adjacent transmitter housing means.
Claim 4
Dependent Claim
52 words
An arrangement according to claim 1, in which at least one of the sections of said housing means is provided with means for permitting a radial displacement of said sections relative to each other while preventing said sections from moving relative to each other in the axial direction of said working rollers.
Claim 5
Dependent Claim
25 words
An arrangement according to claim 3, in which said means include webs respectively connected to said upper and lower sections slidable relative to each other.
