ABSTRACT:
A filter cigarette making machine wherein the web which is to yield adhesive-coated uniting bands is flexed by a curling device before it reaches the paster. The curling device is rigid with or is movable relative to a supporting device which is mounted in the frame of the filter cigarette making machine. A safety device can be activated to disengage the web from the curling device during starting of the web and/or to temporarily disengage the web from the curling device when a splice in the web approaches the curling station. The safety device has a rod which can bodily disengage the web from the edge of the curling device or a shaft which can rotate the supporting device to thereby move the curling device out of the way.
