Abstract

A finger-protection device for a roller gap of a paper-calender with heated rollers has a hollow body (4) extending along the roller gap, with a front wall (5) facing a roller (3), defining the roller gap, a dome shaped rear wall (6), and two end walls (8). The strips (9, 10) forming the longitudinal edges of the front and rear walls are at an angular position in relation to the front and rear walls (5, 6) and are directed to the rollers (2, 3) limiting the roller gap. They provide a maximum distance (d) from the rollers (2, 3), which does not permit the passing through of one's fingers between a longitudinal edge and the adjacent roller (2, 3). The hollow body (4) is supported at its ends and can be adjusted relative to the rollers (2, 3). In order to simplify the manufacture and operational handling of the finger-protection device (1, 2) and also maintain a non-exceedable maximum distance (d) to the rollers during the operation, the hollow body (4 ) consists of fiber-reinforced synthetic resin plastic. The front and rear walls (5, 6) are made as separate units and connected to each other. The strips are formed by front and rear walls (5, 6) as a one piece construction and as flanges (9a, 9b; 10a, 10b) connected to each other. The end walls (8) are produced separately and connected to the front and rear walls (5, 6) or are produced as a one-piece unit with one of the front and rear walls.
