Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
196 words
An apparatus for wrapping blanks around a mandrel positioned adjacent said apparatus, comprising: a base having a face having a concave configuration for receiving a portion of the mandrel and being movable between a first position at which the concave face is spaced from the mandrel and an intervening blank positioned adjacent said concave face and a second position at which portions of the blank and the mandrel are within the concave face; means for moving the base relative to said mandrel between the first and second positions; first and second wings each having first and second end portions with each wing being pivotally attached at the first end portion to a separate end of the concave face of the base and movable between a first position at which each wing is spaced from the mandrel and the intervening blank and a second position at which each wing is forcefully urging a portion of the blank against a portion of the mandrel; and means for moving the first and second wings between the first and second positions at a rate relative to and in response to, movement of the base between the first and second positions.
Claim 2
Independent Claim
196 words
An apparatus for wrapping blanks around a mandrel positioned adjacent said apparatus, comprising: a base having a face having a concave configuration for receiving a portion of the mandrel and being movable between a first position at which the concave face is spaced from the mandrel and an intervening blank positioned adjacent said concave face and a second position at which portions of the blank and the mandrel are within the concave face; means for moving the base relative to said mandrel between the first and second positions; first and second wings each having first and second end portions with each wing being pivotally attached at the first end portion to a separate end of the concave face of the base and movable between a first position at which each wing is spaced from the mandrel and the intervening blank and a second position at which each wing is forcefully urging a portion of the blank against a portion of the mandrel; and means for moving the first and second wings between the first and second positions at a rate relative to and in response to, movement of the base between the first and second positions.
Claim 3
Dependent Claim
73 words
An apparatus, as set forth in claim 1, further including a track extending along the direction of movement of the base; first and second rollers each fixedly attached at the axis to a first end portion of a separate wing and in rolling contact with the track for pivotally moving each wing between the first and second positions in response to movement of the rollers in response to reciprocal movement of the base.
Claim 4
Dependent Claim
47 words
An apparatus, as set forth in claim 2, wherein the dimensions of the rollers are sized so that at the first position of the base the wings are at their first position and at the second position of the base the wings are at their second position.
Claim 5
Dependent Claim
56 words
An apparatus, as set forth in claim 1, wherein portions of the first wing at the first position are spaced a greater distance from the mandrel than the corresponding portion of the second wing and the second wing reaches the second position before the first wing for placing the blank in overlapping relation about the mandrel.
Claim 6
Dependent Claim
53 words
An apparatus, as set forth in claim 1, further including a holding means contacting and urging the blank against the mandrel upon initiation of movement of the base from the first toward the second position and releasing the blank upon initiation of movement of the base from the second toward the first position.
Claim 7
Dependent Claim
31 words
An apparatus, as set forth in claim 1, wherein at the second position of the wings the second end portion of the wings are spaced a distance one from the other.
Claim 8
Dependent Claim
40 words
An apparatus, as set forth in claim 1, further including a sealing means for contacting and sealing edge portions of the blank one to the other upon arrival of the wings at their second position and thereafter releasing the blank.
Claim 9
Dependent Claim
75 words
An apparatus, as set forth in claim 1, further including a rack extending along the direction of movement of the base; first and second pinion gears each fixedly attached at the axis to a first end portion of a separate wing and in rolling contact with the rack for pivotally moving each wing between the first and second positions in response to movement of the pinion gears in response to reciprocal movement of the base.
Claim 10
Dependent Claim
48 words
An apparatus, as set forth in claim 8, wherein the dimensions of the pinion gears are sized so that at the first position of the base the wings are at their first position and at the second position of the base the wings are at their second position.
