A cigarette filter comprises an elongate filter component having a longitudinal axis. A plurality of spaced apart slits generally perpendicular to the longitudinal axis of the filter component partially extend into the component. The slits enable the filter to disintegrate and more readily degrade after being used and discarded. Processes and apparatus are provided for producing such cigarette filters.

A dispenser adapter to improve the dispensing of thin webs from rolls of material contained in conventional dispensing boxes is specially configured to provide its benefits of antirecoil and risk free tearing to a wide range of dispensing boxes. The adapter is particularly suited to being retrofitted to commercially available dispensing boxes containing a wide range of materials such as plastic wrap, aluminum foil, and wax paper, while allowing the user to dispense these various materials by a s...

A shear mechanism for cutting worn out vehicle tires into arcuate segments to facilitate storage and transportation. First and second vertically extending anvil members are mounted on a base in parallel, spaced-apart relationship to one another. The anvil members include removable female die members. Pivotally joined to the base is a blade member, the blade member also having a replaceable working edge. The blade is driven by a hydraulic ram and when a tire is positioned against the anvil and th...

A knife sharpener includes an abrasive cylinder and a rectangular block for sharpening the opposed portions of a knife edge. The cylinder and block are urged together to form a sharpening notch in which the knife edge is received. The knife sharpener is particularly adapted for food slicing machines. The abrasive cylinder and block are mounted within a housing that is connected to a handle by the neck. The neck may be jointed to enable the housing to be positioned relative to the housing so that...

A ribbon cutting apparatus which solves the problems of lateral shifting, stretching and shrinking of a printed web of material by providing a plurality of blade carrying blocks each of which may be independently positioned with respect to a travelling web. Each blade carrying block supports between 2 and 9 circular blades. Each of the blades in turn is connected to a small pneumatic cylinder which presses the blades against a platen roller so as to crush cut the web of material passing through....

A plate subdividing and sorting machine includes a variegated subdividing device which subdivides the respective plate blank into final products arranged in the thus subdivided plate blank in respective longitudinal and transverse strips. The subdivided plate blank is shifted onto a stripping-off tray with which there is associated a stripping arrangement which strips the respective longitudinal strips off of the stripping-off tray and onto distributing roller conveyors which distributes the fin...

A leader tape housing is provided with a compartment for mounting a reel with a leader tape thereon. A guide is provided for changing the path of the tape and the plane of the tape. A feeder device is provided in the housing which includes a first roller and a second roller forming a nip therebetween, the second roller being provided with a manually operable handle for driving it. The second roller includes a pair of diametrically opposed arc segments and a pair of diametrically opposed flats, s...

A cutting knife for a rotary cutting apparatus for multilayer isolated paper products with projections, for example in tooth form, projecting from a base body. The projections are formed as blades or the like displaceable in or on the base body and inclined with respect to a cutting plane; the faces of the blades lying in the cutting plane can be reground.

A die assembly for mounting in a die press operates to punch a row of holes in a stack of paper sheets in response to a single press stroke. The die assembly comprises a stationary lower die block having a row of die holes therethrough, one or more lubricated stationary guide plates each having a row of guide holes therethrough and located above and spaced from the die block by a separator plate so as to define a stack-receiving slot, a reciprocably movable punch retainer assembly located above ...

A system for processing a virgin web to yield printed documents such as business forms comprises a printing device adapted for printing non-repetitive (variable) and repetitive (constant) information and data as determined by a computer, and processing devices disposed--in relation to the transporting direction of the web--in front of and past the printing device and serving for shaping the web and possibly for printing onto the web in color. The processing devices are preferably built in the fo...
