Claim 9

Dependent Claim 37 words

The method according to claim 1, further including the step of synchronizing the steps of claim 1, so that an envelope is delivered to said inserting location prior to the step of pushing inserts into an envelope.

Claim 10

Dependent Claim 242 words

An inserter station for inserting of inserts into envelopes, comprising: an inserting location; means for conveying inserts to said inserting location, said means for conveying including a top plate along and upon which inserts are conveyed to said inserting location; gripper drum means for delivering envelopes to said inserting location, said gripper drum means including a rotatable gripper drum having a periphery upon which envelopes are carried and delivered to said inserting location, said periphery being disposed proximally to said inserting location, said gripper drum means including means for holding the bottom face of an envelope while the envelope is disposed in said inserting location; means for lifting open the top side of an envelope while the envelope is disposed in said inserting location, said means for lifting being cooperative with said means for holding to open an envelope for insertion of inserts; means for guiding inserts for insertion into the envelopes while envelopes are disposed in said inserting location, said means for guiding including fingers that are selectively rotatable into opened envelopes in said inserting location; and, insert pusher means for pushing inserts between said fingers into opened envelopes disposed in said inserting location, said insert pusher means including at least one driven pusher having an irrotationally translatable insert-engaging face, said at least one driven pusher being translationally driven so that said insert-engaging face moves from a retracted position beneath said top plate to a forward position above said top plate.

Claim 11

Dependent Claim 242 words

An inserter station for inserting of inserts into envelopes, comprising: an inserting location; means for conveying inserts to said inserting location, said means for conveying including a top plate along and upon which inserts are conveyed to said inserting location; gripper drum means for delivering envelopes to said inserting location, said gripper drum means including a rotatable gripper drum having a periphery upon which envelopes are carried and delivered to said inserting location, said periphery being disposed proximally to said inserting location, said gripper drum means including means for holding the bottom face of an envelope while the envelope is disposed in said inserting location; means for lifting open the top side of an envelope while the envelope is disposed in said inserting location, said means for lifting being cooperative with said means for holding to open an envelope for insertion of inserts; means for guiding inserts for insertion into the envelopes while envelopes are disposed in said inserting location, said means for guiding including fingers that are selectively rotatable into opened envelopes in said inserting location; and, insert pusher means for pushing inserts between said fingers into opened envelopes disposed in said inserting location, said insert pusher means including at least one driven pusher having an irrotationally translatable insert-engaging face, said at least one driven pusher being translationally driven so that said insert-engaging face moves from a retracted position beneath said top plate to a forward position above said top plate.

Claim 12

Dependent Claim 44 words

The inserter station according to claim 9, wherein said means for lifting includes suction cup means for engaging, lifting, holding, and releasing the top side of an envelope by action of vacuum selectively valved thereto while the envelope is disposed in said inserting location.

Claim 13

Dependent Claim 35 words

The inserter station according to claim 9, wherein said means for holding includes vacuum means for selectively holding and releasing envelopes to and from said periphery, respectively, while envelopes are disposed in said inserting location.

Claim 14

Dependent Claim 32 words
