Abstract
A shoe press for a paper or board machine, comprising a press shoe and a counter roll, which between themselves form an extended nip for a paper or cardboard web and a circulated flexible belt, and a plurality of hydraulic loading cylinders which are arranged between a horizontal beam included in the frame system of the shoe press and the press shoe and adapted to press the press shoe against the counter roll, the pistons of the loading cylinders being fixedly connected to the horizontal beam. The working chambers of the loading cylinders are supplied with fluid by a common duct formed in an elongate duct member which is affixed to the beam. A vertical duct is formed in the piston of each loading cylinder and is connected to the common duct. The duct member is releasably affixed to the beam by eccentric clamping members which are fixable in multiple positions on the beam for selectively placing different portions of the clamping members in engagement with grooves formed in opposite sides of the duct member, such that the duct member and loading cylinders can be shifted as a unit in the machine direction of the shoe press.
