ABSTRACT OF THE DISCLOSURE This invention relates to a device for collecting solid or fluid waste on which one end of a tube (7) made by thin, flexible and preferably impermeable material of considerable length which is folded or pleated in an accordian-like fashion and kept outside a funnel-shaped body (4), from where it is advanced over the upper edge of the body (4) through a duct (5) through the body (4). Under the duct (5) there is a waste-receiving chamber to which the tube (7) is advanced by means of the duct (5) and a feed mechanism (8) arranged to feed a predecided length of the tube (7) and its contents into the waste receiving chamber. The feeding mechanism (8) consists of two opposite rollers (16, 17) which are transversed in relation to the feeding direction of the tube (7) and between which the tube (7) is advanced and which are brought to rotate in opposite direc- tions at mainly equal speed in the feeding movement and which are equipped with radially pertruding flanges (18) which are elongated along the full length of said rollers. According to the invention the rollers (16, 17) of which at least one is mounted to allow it to springingly be slid in one direction transverse to said feeding direction at elast as much as equal to the smallest elongation of the cross-section of the duct (5). Further- more the radially pertruding flanges (18) at the gables of the rollers (16, 17) are equipped with tilted sliding surfaces (29) onto which the points of the flanges of the other roller are arranged to slide when the rollers rotate allowing a space to arise for the collected waste between the flanges (18) during the feeding.
