Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
195 words
A packaging machine for rodlike articles comprising a conveyor moving in a closed path, said conveyor having fixedly mounted thereon a plurality of spaced independent open ended arbors each mounted on the conveyor with its longitudinal axis transverse to the direction of movement of said conveyor a Ushaped member secured to said conveyor and extending about said arbor, the open end of said U-shaped member lying parallel to the axis of said arbor and exposing one side thereof, a roller, means mounting said roller on a movable support adjacent said arbor, said movable support being fixed to said conveyor so as to be conjointly movable with said arbor on said conveyor and pivotable relative thereto to move the roller toward the surface of said arbor, means for feeding foil or paper web to said arbor through the open end of said U-shaped member between the surface of said arbor and said roller, and means for causing said roller to pivot to engage the web and slide the same about the surface of said arbor between it and the surface of said U-shaped member to thereby cause said web to assume the shape of said arbor.
Claim 2
Dependent Claim
195 words
A packaging machine for rodlike articles comprising a conveyor moving in a closed path, said conveyor having fixedly mounted thereon a plurality of spaced independent open ended arbors each mounted on the conveyor with its longitudinal axis transverse to the direction of movement of said conveyor a Ushaped member secured to said conveyor and extending about said arbor, the open end of said U-shaped member lying parallel to the axis of said arbor and exposing one side thereof, a roller, means mounting said roller on a movable support adjacent said arbor, said movable support being fixed to said conveyor so as to be conjointly movable with said arbor on said conveyor and pivotable relative thereto to move the roller toward the surface of said arbor, means for feeding foil or paper web to said arbor through the open end of said U-shaped member between the surface of said arbor and said roller, and means for causing said roller to pivot to engage the web and slide the same about the surface of said arbor between it and the surface of said U-shaped member to thereby cause said web to assume the shape of said arbor.
Claim 3
Dependent Claim
89 words
The device according to claim 1 in which means for folding the web about the arbor comprises a pair of pivotally connected arms encircling said arbor, said arms being pivoted about an axis lying parallel to the axis of said arbor and to the exterior of the bight of the U-shaped member to permit the free ends thereof to engage said web at opposed edges of the exposed side of said arbor to thereby fold the web about the arbor in a direction parallel to the longitudinal axis thereof.
Claim 4
Dependent Claim
36 words
The device according to claim 2 including a pair of pivoting arms positionable along the exposed side of the arbor and movable to engage the edges of the web and adjust its position prior to folding.
Claim 5
Dependent Claim
69 words
The device according to claim 3 including a stop member adapted to engage the web and hold the same against the action of the roller, a pair of movable pressure pads, means supporting each of said pads independently for movement against the exposed side of the arbor and means to impress said pads against the web after the web has been folded across the free side of the arbor.
Claim 6
Dependent Claim
78 words
The device according to claim 4, including means for providing the package with bottom folds comprising an upper and a lower pressure plate, means for movably mounting said plates in opposed directions to each other in a common plane parallel to the end of said arbor and perpendicular to the longitudinal axis thereof and means for moving said plate to effect the folding of the web after said web is folded about the exposed side of said arbor.
Claim 7
Dependent Claim
96 words
The device according to claim 1 including a second conveyor having a plurality of containers in which a predetermined number of articles are arranged, said containers corresponding in number and position to the number and position of said arbors, said conveyors extending about coaxial arcuate members during a portion of their travel, extending rectilinearly in angular directions therefrom during the remainder of their travel the containers being filled with said articles and said packages wrapped in the rectilinear sections of travel, the device including means for transfering said articles to said packs in the arcuate section.
Claim 8
Dependent Claim
50 words
The device according to claim 6 including means for independently feeding a foil web and a paper web and means for synchronizing the action of said roller with the feeding of said web so as to successively wrap first the foil web and then the paper web about the arbor.
Claim 9
Dependent Claim
29 words
The device according to claim 7 including means for transfering articles from the first conveyor into the formed pack and means for creating the top fold on said pack.
Claim 10
Dependent Claim
59 words
The device according to claim 8 including means for detecting the presence or absence of a foil, and means for producing a signal indicative thereof, and means for preventing operation of paper wrapper mechanism in the absence of a properly formed foil and for preventing transfer of the articles in absence of a properly formed foil or paper wrapper.
