Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
145 words
In an apparatus for making hollow bodies from flat blanks having side edges, said blanks being formed into hollow bodies around an elongated mandrel with said side edges overlapping one another and having adhesive interposed therebetween to define a side seam, said apparatus including reciprocating feed means for feeding said bodies from station-to-station in a feed direction along said mandrel, the improvement comprising; first hammer means movable toward and away from said mandrel for engaging said side seam, first program means for moving said first hammer means into engagement with said seam at a predetermined first force at a first station position of said body, said first program means holding said first hammer means in engagement with said seam at a second force less than said first force during movement of said body from said first station to a second station by said feed means.
Claim 2
Dependent Claim
145 words
In an apparatus for making hollow bodies from flat blanks having side edges, said blanks being formed into hollow bodies around an elongated mandrel with said side edges overlapping one another and having adhesive interposed therebetween to define a side seam, said apparatus including reciprocating feed means for feeding said bodies from station-to-station in a feed direction along said mandrel, the improvement comprising; first hammer means movable toward and away from said mandrel for engaging said side seam, first program means for moving said first hammer means into engagement with said seam at a predetermined first force at a first station position of said body, said first program means holding said first hammer means in engagement with said seam at a second force less than said first force during movement of said body from said first station to a second station by said feed means.
Claim 3
Dependent Claim
145 words
In an apparatus for making hollow bodies from flat blanks having side edges, said blanks being formed into hollow bodies around an elongated mandrel with said side edges overlapping one another and having adhesive interposed therebetween to define a side seam, said apparatus including reciprocating feed means for feeding said bodies from station-to-station in a feed direction along said mandrel, the improvement comprising; first hammer means movable toward and away from said mandrel for engaging said side seam, first program means for moving said first hammer means into engagement with said seam at a predetermined first force at a first station position of said body, said first program means holding said first hammer means in engagement with said seam at a second force less than said first force during movement of said body from said first station to a second station by said feed means.
Claim 4
Dependent Claim
145 words
In an apparatus for making hollow bodies from flat blanks having side edges, said blanks being formed into hollow bodies around an elongated mandrel with said side edges overlapping one another and having adhesive interposed therebetween to define a side seam, said apparatus including reciprocating feed means for feeding said bodies from station-to-station in a feed direction along said mandrel, the improvement comprising; first hammer means movable toward and away from said mandrel for engaging said side seam, first program means for moving said first hammer means into engagement with said seam at a predetermined first force at a first station position of said body, said first program means holding said first hammer means in engagement with said seam at a second force less than said first force during movement of said body from said first station to a second station by said feed means.
Claim 5
Dependent Claim
41 words
The device of claim 1 and further including movable first carrier means for carrying said first hammer means, and yieldable biasing means on said carrier for normally biasing said first hammer means away from said first carrier means toward said mandrel.
Claim 6
Dependent Claim
21 words
The device of claim 2 wherein said first program means comprises rotatable first cam means for engaging said first carrier means.
Claim 7
Dependent Claim
108 words
The device of claim 1 and further including second hammer means movable toward and away from said mandrel for engaging said side seam at a second station of said bodies, said second hammer means being positioned adjacent said first hammer means in said feed direction of said bodies, second program means for holding said second hammer means in engagement with said seam at a predetermined first holding force during forward feeding movement of said feed means, said second program means holding said second hammer means in engagement with said seam at a second holding force greater than said first holding force during retracting movement of said feed means.
Claim 8
Dependent Claim
41 words
The device of claim 4 and further including movable second carrier means for carrying said second hammer means, and yieldable biasing means on said carrier for normally biasing said second hammer means away from said second carrier means toward said mandrel.
Claim 9
Dependent Claim
21 words
The device of claim 5 wherein said second program means comprises rotatable second cam means for engaging said second carrier means.
Claim 10
Dependent Claim
44 words
The device of claim 4 and further including movable first and second carrier means for carrying said first and second hammer means, and yieldable biasing means on said carrier means for normally biasing said hammer means away from said carrier means toward said mandrel.
Claim 11
Dependent Claim
24 words
The device of claim 7 wherein said first and second program means comprise rotatable cam means for engaging said first and second carrier means.
Claim 12
Independent Claim
72 words
A method of bonding side seams defined by overlapped side edges and hollow bodies having adhesive interposed therebetween as said bodies are moved along an elongated mandrel from station-to-station by feed means, comprising the steps of; applying a first force to said seams at a first station, applying a second force less than said first force to said seams as said bodies are moved from said first station to a second station.
Claim 13
Independent Claim
72 words
A method of bonding side seams defined by overlapped side edges and hollow bodies having adhesive interposed therebetween as said bodies are moved along an elongated mandrel from station-to-station by feed means, comprising the steps of; applying a first force to said seams at a first station, applying a second force less than said first force to said seams as said bodies are moved from said first station to a second station.
Claim 14
Dependent Claim
50 words
The method of claim 9 and further including the step of applying a first holding force to said seams as said bodies are moved to said second station, and applying a second holding force greater than said first holding force to said seams at said second station of said bodies.
