Abstract
A shower pipe assembly useable in the papermaking process includes a shower pipe, including structure for oscillating the shower pipe along an axial path and a base. Oscillating support structure couple the base to the shower pipe and supports the shower pipe wherein oscillation of the shower pipe is constrained along a straight line path. The assembly further includes a first arm rotatable about a first axis being stationary relative to the base during rotation of the first arm. A second arm is rotatable about a second axis extending through the first arm such that the distance between the first axis and second axis remains constant. The second arm should be of a length relative to the distance between the first and second axis to produce a straight line motion at a particular location of the second arm upon rotation of the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis. The apparatus further includes structure for rotating the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis to produce a straight line motion at a particular location on the second arm…
