Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 153 words
In combination with a moving web of paper or the like, a glue applicator for applying glue to said moving web comprising: a glue pump including a housing therefor, said housing being formed with an inlet for glue and a discharge nozzle, means mounting said housing in close proximity to said web with said discharge nozzle positioned for applying the discharged glue directly from said nozzle to said moving web, a rotating member associated with said moving web and rotating at a speed proportional to the speed of said web, a rotatable rod of noncircular cross section for driving said pump, said pump including a driven gear formed with a through opening having a cross section complementary to the cross section of said rotatable rod and receiving the latter therethrough, means interconnecting said rotating member and said rod for driving said pump at a speed proportional to the speed of said moving web.
Claim 2
Dependent Claim 153 words
In combination with a moving web of paper or the like, a glue applicator for applying glue to said moving web comprising: a glue pump including a housing therefor, said housing being formed with an inlet for glue and a discharge nozzle, means mounting said housing in close proximity to said web with said discharge nozzle positioned for applying the discharged glue directly from said nozzle to said moving web, a rotating member associated with said moving web and rotating at a speed proportional to the speed of said web, a rotatable rod of noncircular cross section for driving said pump, said pump including a driven gear formed with a through opening having a cross section complementary to the cross section of said rotatable rod and receiving the latter therethrough, means interconnecting said rotating member and said rod for driving said pump at a speed proportional to the speed of said moving web.
Claim 3
Dependent Claim 19 words
The combination of claim 1 wherein said pump is adjustable to different positions along the length of said rod.
Claim 4
Dependent Claim 24 words
The combination of claim 1 wherein said rod is readily removable from said pump to stop the latter and prevent discharge of glue therefrom.
Claim 5
Dependent Claim 25 words
The combination of claim 1 wherein a second pump is mounted in a manner similar to said first mentioned pump and connected to said rod.
Claim 6
Dependent Claim 17 words
The combination of claim 4 wherein said pumps are relatively movable along the length of said rod.
Claim 7
Dependent Claim 56 words
The combination of claim 1 wherein said moving web is reeved about a rotating roller and said mounting means supports said housing for discharging the glue in one direction, and second mounting means for supporting said housing for discharging the glue in substantially the opposite direction when the direction of movement of said web is reversed.
