Abstract

Abstract Continuous movement is imparted to a chain made up of packets which are interconnected in end-to-end spaced relation by means of a pair of endless conveyor elements disposed on opposite sides of the path of movement of the chain of packets, a plurality of spaced projections being provided on each conveyor and being disposed in the space between packets so that movement of the working reaches of the conveyors in the same direction imparts movement to the chain of packets. A continuously rotatable cutting element is mounted alongside the chain of packets and synchronized to swing through the space between adjacent packages and thereby to sever the packets one from another. The cutter element is mounted on a shaft which is parallel to the conveyors and to the path of movement of the chain of packets as viewed in a horizontal plane and which is disposed at an angle to the path of movement of the packets and to the conveyors as viewed in a vertical plane thereby to compensate for movement of the packets during cutting so as to effect a vertical cutting operation.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 138 words
A cutter mechanism for severing at regular intervals a moving chain of packets interconnected with each other in spaced end-toend relation, said mechanism comprising an elongated cutter element rotatably mounted on a shaft disposed in substantial alignment in one plane only with the direction of movement of said chain and spaced from said chain, means for imparting rotary movement to said cutter element which is synchronized with movement of said chain to effect cutting operatioNs between adjacent packets, a main endless driven conveyor disposed with its working reach alongside said chain of packets, and lateral projections formed on said conveyor and interposed between spaced adjacent ends of adjacent packets whereby continuous movement is imparted to said chain, said projections being spaced so as to impart a slight tension force to the portion of said chain between said packets.
Claim 2
Dependent Claim 138 words
A cutter mechanism for severing at regular intervals a moving chain of packets interconnected with each other in spaced end-toend relation, said mechanism comprising an elongated cutter element rotatably mounted on a shaft disposed in substantial alignment in one plane only with the direction of movement of said chain and spaced from said chain, means for imparting rotary movement to said cutter element which is synchronized with movement of said chain to effect cutting operatioNs between adjacent packets, a main endless driven conveyor disposed with its working reach alongside said chain of packets, and lateral projections formed on said conveyor and interposed between spaced adjacent ends of adjacent packets whereby continuous movement is imparted to said chain, said projections being spaced so as to impart a slight tension force to the portion of said chain between said packets.
Claim 3
Dependent Claim 157 words
A cutter mechanism for severing at regular intervals a moving chain of packets interconnected with each other in spaced end-to-end relation, said mechanism comprising an elongated cutter element rotatably mounted on a shaft disposed in substantial alignment in one plane only with the direction of movement of said chain and spaced from said chain, means for imparting rotary movement to said cutter element which is synchronized with movement of said chain to effect cutting operations between adjacent packets, a main endless driven conveyor disposed with its working reach alongside said chain of packets, lateral projections formed on said conveyor and interposed between spaced adjacent ends of adjacent packets whereby continuous movement is imparted to said chain, said conveyor and said cutter element being disposed on opposite sides of said chain of packets, and a vertical slot formed in each of said projections and disposed to receive and allow passage therethrough of a part of said cutter element.
Claim 4
Dependent Claim 157 words
A cutter mechanism for severing at regular intervals a moving chain of packets interconnected with each other in spaced end-to-end relation, said mechanism comprising an elongated cutter element rotatably mounted on a shaft disposed in substantial alignment in one plane only with the direction of movement of said chain and spaced from said chain, means for imparting rotary movement to said cutter element which is synchronized with movement of said chain to effect cutting operations between adjacent packets, a main endless driven conveyor disposed with its working reach alongside said chain of packets, lateral projections formed on said conveyor and interposed between spaced adjacent ends of adjacent packets whereby continuous movement is imparted to said chain, said conveyor and said cutter element being disposed on opposite sides of said chain of packets, and a vertical slot formed in each of said projections and disposed to receive and allow passage therethrough of a part of said cutter element.
Claim 5
Dependent Claim 176 words
A cutter mechanism for severing at regular intervals a moving chain of packets interconnected with each other in spaced end-to-end relation, said mechanism comprising an elongated cutter element rotatably mounted on a shaft disposed in substantial alignment in one plane only with the direction of movement of said chain and spaced from said chain, means for imparting rotary movement to said cutter element which is synchronized with movement of said chain to effect cutting operations between adjacent packets, a main endless driven conveyor disposed with its working reach alongside said chain of packets, lateral projections formed on said conveyor and interposed between spaced adjacent ends of adjacent packets whereby continuous movement is imparted to said chain, an auxiliary driven endless conveyor disposed with its working reach alongside said chain of packets and on the opposite side thereof from said main conveyor, and lateral projections formed on said auxiliary conveyor and interposed between spaced adjacent ends of adjacent packets, the outfeed end of said auxiliary conveyor being spaced upstream from the outfeed end of said main conveyor.
Claim 6
Dependent Claim 176 words
A cutter mechanism for severing at regular intervals a moving chain of packets interconnected with each other in spaced end-to-end relation, said mechanism comprising an elongated cutter element rotatably mounted on a shaft disposed in substantial alignment in one plane only with the direction of movement of said chain and spaced from said chain, means for imparting rotary movement to said cutter element which is synchronized with movement of said chain to effect cutting operations between adjacent packets, a main endless driven conveyor disposed with its working reach alongside said chain of packets, lateral projections formed on said conveyor and interposed between spaced adjacent ends of adjacent packets whereby continuous movement is imparted to said chain, an auxiliary driven endless conveyor disposed with its working reach alongside said chain of packets and on the opposite side thereof from said main conveyor, and lateral projections formed on said auxiliary conveyor and interposed between spaced adjacent ends of adjacent packets, the outfeed end of said auxiliary conveyor being spaced upstream from the outfeed end of said main conveyor.
Claim 7
Dependent Claim 29 words
