Abstract
Abstract A packing machine wherein blocks of cigarettes are wrapped to form packs and/or wherein cigarette packs are provided with transparent outer envelopes comprises intermittently operated conveyors for envelopes and their contents. The conversion of tinfoil, paper and/or transparent plastic blanks into envelopes involves a series of treatments including one or more treatments each of which can be completed within a first period whose length equals the sum of an interval of stepwise movement and an interval of dwell of the respective conveyor, and one or more second treatments each of which can be completed within a longer second period. When the machine receives a stop signal, its operation continues until after the completion of a treatment which is in progress when the stop signal is being produced, regardless of whether the started treatment is a first or a second treatment. Consequently, all blanks which undergo treatment at the time a stop signal is being produced are processed to a degree which is necessary to insure that such blanks need not be discarded when the machine is started again.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
A method of manipulating containers and their contents, particularly for the making, filling and sealing of packs for tobacco-containing articles or analogous commodities comprising the steps of subjecting at least the containers to a plurality of successive treatments including at least one first treatment whose completion necessitates a first period of time and at least one second treatment whose completion necessitates a different second period of time; completing each such treatment once the treatment is started; conveying a series of said commodities along a first path; transferring successive commodities of said series into a second path; introducing into said second path a container for each transferred commodity, said step of subjecting said containers to said plurality of treatments taking place while such containers are located in said second path; interrupting the transfer of commodities into said second path; and terminating the introduction of containers into said second path so that the number of containers in said second path following said interrupting step equals the number of commodities in said second path.
Claim 2
Independent Claim
171 words
A method of manipulating containers and their contents, particularly for the making, filling and sealing of packs for tobacco-containing articles or analogous commodities comprising the steps of subjecting at least the containers to a plurality of successive treatments including at least one first treatment whose completion necessitates a first period of time and at least one second treatment whose completion necessitates a different second period of time; completing each such treatment once the treatment is started; conveying a series of said commodities along a first path; transferring successive commodities of said series into a second path; introducing into said second path a container for each transferred commodity, said step of subjecting said containers to said plurality of treatments taking place while such containers are located in said second path; interrupting the transfer of commodities into said second path; and terminating the introduction of containers into said second path so that the number of containers in said second path following said interrupting step equals the number of commodities in said second path.
Claim 3
Dependent Claim
92 words
A method as defined in claim 1, further comprising the steps of conveying the containers and their contents stepwise for first intervals of time and maintaining the containers and their contents at rest for second intervals of time which alternate with said first intervals, each of said first periods being at most equal to the sum of m first and m second intervals and each of said second periods being at most equal to the sum of n+m first intervals and n+m second intervals, m and n being whole numbers including one.
Claim 4
Dependent Claim
23 words
A method as defined in claim 2, wherein each of said second periods is a whole multiple of one of said first periods.
Claim 5
Dependent Claim
20 words
A method as defined in claim 1, wherein one of said treatments includes introducing said commodities into the respective containers.
Claim 6
Dependent Claim
46 words
A method as defined in claim 1, further comprising the steps of conveying successive commodities from said first path into a third path in response to interruption of the transfer of such commodities into said second path, and storing the commodities which enter said third path.
Claim 7
Dependent Claim
241 words
A machine for manipulating containers and their contents, particularly a machine for the making, filling and sealing of packs for tobacco-containing articles or analogous commodities, comprising first transporting means for conveying bodies each of which constitutes at least a part of a container along at least one first path; second transporting means for conveying commodities along at least one second path for assembly with containers; converting means operative to subject said bodies to a plurality of treatments including at least one first treatment whose completion necessitates a first period of time and at least one second treatment whose completion necessitates a different second period of time; control means for said converting means, including means for producing signals to initiate interruptions in the operation of said converting means and means for delaying such interruptions until after the completion of a treatment during which a signal is produced; transfer means operative to transfer successive commodities from said second path into said first path, said control means comprising means for terminating the operation of said transfer means in response to said signals; and feeding means operative to supply said bodies to said first transporting means, one for each commodity which is being delivered by said transfer means, said control means comprising means for terminating the operation of said feeding mEans in response to said signals so that the number of bodies in said first path equals the number of commodities in said first path.
Claim 8
Dependent Claim
241 words
A machine for manipulating containers and their contents, particularly a machine for the making, filling and sealing of packs for tobacco-containing articles or analogous commodities, comprising first transporting means for conveying bodies each of which constitutes at least a part of a container along at least one first path; second transporting means for conveying commodities along at least one second path for assembly with containers; converting means operative to subject said bodies to a plurality of treatments including at least one first treatment whose completion necessitates a first period of time and at least one second treatment whose completion necessitates a different second period of time; control means for said converting means, including means for producing signals to initiate interruptions in the operation of said converting means and means for delaying such interruptions until after the completion of a treatment during which a signal is produced; transfer means operative to transfer successive commodities from said second path into said first path, said control means comprising means for terminating the operation of said transfer means in response to said signals; and feeding means operative to supply said bodies to said first transporting means, one for each commodity which is being delivered by said transfer means, said control means comprising means for terminating the operation of said feeding mEans in response to said signals so that the number of bodies in said first path equals the number of commodities in said first path.
Claim 9
Dependent Claim
111 words
