Abstract:
The invention relates to a device ( 10 ) to dispense paper sections of a predetermined length, comprising a device ( 26 ), operated by pulling on an end ( 74 ) of the paper web, for separating the paper sections from a paper web ( 24 ) wound onto a paper roll ( 22 ), and to provide easy manual access to the paper web ( 24 ) that follows after the separated paper section has been released, whereby the device ( 26 ) comprises at least one cutting roller ( 40 ) with a width that corresponds to at least the entire width of the paper web and a knife ( 42 ) that extends substantially over the entire side of the roller and protrudes rigidly from a roller shell, whereby associated with the cutting roller ( 40 ) is a pressure roller ( 44 ), which has a slit-shaped opening ( 46 ) that corresponds to the knife and is coupled to the cutting roller via geared wheels ( 52, 56; 54, 58 ). In order to be able to cut and automatically dispense paper web of high strength and elasticity in a reliable and trouble-free manner, it is intended that a geared wheel ( 52, 56; 54, 58 ), which is coupled to the cutting roller ( 40 ) or to the pressure roller ( 44 ), is eccentrically coupled to a tension spring ( 80 ), that pulling the end ( 74 ) of the paper web results in the paper web ( 24 ) being stretched tightly over a circumferential surface ( 72 ) of the pressure roller ( 44 ), and being sectionally cut, while maintaining some uncut strands, by the penetration of the knife ( 42 ) from the outside into the slit-shaped opening ( 46 ), in order to effect both a severing of the paper section as well as an elongation of the tension spring ( 80 ) up to a turn-around point, and that after the turn-around point has been overcome, both the cutting roller ( 40 ) and the pressure roller ( 44 ) continue to be rotated in opposite directions by the contraction of the tension spring ( 80 ) to dispense the paper section and a new paper end.

Claim (Index 5):
The device of  claim 1 ,\n characterized in that the knife ( 42 ) comprises a knife blade ( 114 ) with teeth ( 120 ,  126 ) and/or groups of teeth ( 122 ,  124 ), which are spaced apart along the length of the blade ( 114 ), whereby the teeth ( 120 ,  126 ) and/or groups of teeth ( 122 ,  124 ) are separated from each other by cut-outs ( 128 ,  130 ,  132 ), and in that each of the cut-outs ( 128 ,  130 ,  132 ) comprises two cutting edges ( 162 ,  164 ,  166 ,  168 ), which extend parallel to each other and transversely to the longitudinal extent of the knife ( 42 ), and in that at least one of the cutting edges ( 162 ,  164 ,  166 ,  168 ) is a cutting edge of a tooth ( 120 ,  126 ) bordering the cut-out ( 128 ,  132 ) or of the group of teeth ( 122 ,  124 ) bordering the cut-out ( 128 ,  130 ,  132 ).
