Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A method for inserting material into an envelope using an inserting machine, said envelope having a front panel, a back panel, and a flap connected to said front panel to overlap said back panel, the method including the steps of: transporting the envelope towards an inserting station of said machine on a transport means of said machine; deflecting at least portions of selected pieces of insertion material from stacks of insertion material respectively contained at a plurality of insertion supply stations proximate said transport means, said deflection being accomplished by applying to said selected pieces for a period of time a vacuum, said vacuum being applied through a suction means situated at each insertion supply station of said machine; extracting said selected pieces from each insertion supply station and depositing said selected pieces on said transport means; inserting said selected pieces into said envelope at said inserting station; and, selectively adjusting for each individual insertion supply station the period of time for the application of said vacuum through said suction means.
Claim 2
Independent Claim
171 words
A method for inserting material into an envelope using an inserting machine, said envelope having a front panel, a back panel, and a flap connected to said front panel to overlap said back panel, the method including the steps of: transporting the envelope towards an inserting station of said machine on a transport means of said machine; deflecting at least portions of selected pieces of insertion material from stacks of insertion material respectively contained at a plurality of insertion supply stations proximate said transport means, said deflection being accomplished by applying to said selected pieces for a period of time a vacuum, said vacuum being applied through a suction means situated at each insertion supply station of said machine; extracting said selected pieces from each insertion supply station and depositing said selected pieces on said transport means; inserting said selected pieces into said envelope at said inserting station; and, selectively adjusting for each individual insertion supply station the period of time for the application of said vacuum through said suction means.
Claim 3
Dependent Claim
88 words
The method of claim 1 wherein said machine has a cycle of operation divided into increments, and wherein said selective adjustment step further comprises the steps of: selecting for each of said individual stations a start time to initiate application of said vacuum, said start time corresponding to an increment of the operation cycle of said machine; and, selecting for each of said individual stations an end time to cease application of said vacuum, said end time corresponding to an increment of the operating cycle of said machine.
Claim 4
Dependent Claim
100 words
The method of claim 1 further including the steps of: deflecting at least a portion of said envelope from a stack of envelopes contained at an envelope supply station proximate said transport means, said deflection being accomplished by applying a vacuum to said envelope, said vacuum being applied through a suction means situated at the envelope supply station of said machine; extracting said envelope from said envelope supply station and depositing said envelope on said transport means; and, selectively adjusting the period of time for the application of said vacuum through said suction means situated at said envelope supply station.
Claim 5
Dependent Claim
84 words
The method of claim 3 wherein said machine has a cycle of operation divided into increments, and wherein the improvement further comprises the steps of: selecting a start time to initiate application of said vacuum at said envelope supply station, said start time corresponding to an increment of the operating cycle of said machine; and, selecting an end time to cease application of said vacuum at said envelope supply station, said end time corresponding to an increment of an operation cycle of said machine.
Claim 6
Dependent Claim
161 words
The method of claim 1 wherein said inserting step further includes the steps of: positioning said envelope at said inserting station; separating said front panel of said envelope from said back panel of said envelope, said separation being accomplished by applying to said front panel for a period of time a vacuum, said vacuum being applied through suction means situated below the plane of said transport means at said inserting station, and by applying to said back panel for a period of time a vacuum, said vacuum being applied through suction means situated above the plane of said transport means at said inserting station; selectively adjusting the period of time for the application of said vacuum through said suction means situated below the plane of said transport means at said inserting station; and, selectively adjusting the period of time for the application of said vacuum through said suction means situated above the plane of said transport means at said inserting station.
Claim 7
Dependent Claim
124 words
The method of claim 5 wherein said machine has a cycle of operation divided into increments, and wherein the improvement further comprises the steps of: selecting a start time to initiate application of said vacuum to said suction means below said transport means at said inserting station and to said suction means above said transport means at said inserting station, said start time corresponding to an increment of the operation cycle of said machine; and, selecting an end time to cease application of said vacuum to said suction means below said transport means at said inserting station and to said suction means above said transport means at said inserting station, said end time corresponding to an increment of the operation cycle of said machine.
Claim 8
Dependent Claim
68 words
The method of claim 5 wherein said inserting step further includes the step of: opening the flap of said envelope, said opening being accomplished by applying to said flap a vacuum, said vacuum being applied through a flap-opening suction means situated at said inserting station; and, selectively adjusting the period of time for the application of said vacuum through said flap-opening suction means situated at said inserting station.
Claim 9
Dependent Claim
84 words
The method of claim 7 wherein said machine has a cycle of operation divided into increments, and wherein the improvement further comprises the steps of: selecting a start time to initiate application of said vacuum to said flap-opening suction means, said start time corresponding to an increment of the operation cycle of said machine; and, selecting an end time to cease application of said vacuum to said flap-opening suction means, said end time corresponding to an increment of the operation cycle of said machine.
Claim 10
Dependent Claim
68 words
The method of claim 1 wherein said inserting step further includes the steps of: opening the flap of said envelope, said opening being accomplished by applying to said flap a vacuum, said vacuum being applied through a flap-opening suction means situated at said inserting station; and, selectively adjusting the period of time for the application of said vacuum through said flap-opening suction means situated at said inserting station.
Claim 11
Dependent Claim
84 words
The method of claim 9 wherein said machine has a cycle of operation divided into increments, and wherein the improvement further comprises the steps of: selecting a start time to initiate application of said vacuum to said flap-opening suction means, said start time corresponding to an increment of the operation cycle of said machine; and, selecting an end time to cease application of said vacuum to said flap-opening suction means, said end time corresponding to an increment of the operation cycle of said machine.
