An apparatus for wrapping a sheet about an article moving in one direction comprising a frame, a conveyor on said frame for moving articles in said one direction, a first pair of links pivoted to said frame, a second pair of links respectively pivoted to said first pair of links, a first sheet smoothing and wrapping roller extending between said second pair of links and journaled therein for smoothing and wrapping a wrapping sheet over an article, a pair of arms pivoted respectively to aid second pair of links intermediate the ends thereof, a second roller extending between said pair of arms and journaled therein for wrapping said sheet over said article toward said first roller, said second roller being positioned such as to be contacted by an article being conveyed by said conveyor.
Claim 3
Independent Claim
167 words
An apparatus for wrapping a sheet about an article moving in one direction comprising a frame, a conveyor on said frame for moving articles forwardly in said one direction, a first pair of links pivoted to said frame, a second pair of links respectively pivoted to said first pair of links, a first roller extending between said second pair of links and journaled therein for rolling a wrapping sheet up and over an article, a pair of arms pivoted respectively to said second pair of links intermediate the ends thereof, a second roller extending between said pair of arms and journaled therein, said second roller being positioned such as to be contacted and moved forwardly by an article being conveyed by said conveyor, means for moving said second roller over a surface of an article being conveyed as said roller is being moved forwardly under the urging of an article being conveyed to wrap said wrapping sheet over said surface of the article toward said first roller.
Claim 4
Independent Claim
167 words
An apparatus for wrapping a sheet about an article moving in one direction comprising a frame, a conveyor on said frame for moving articles forwardly in said one direction, a first pair of links pivoted to said frame, a second pair of links respectively pivoted to said first pair of links, a first roller extending between said second pair of links and journaled therein for rolling a wrapping sheet up and over an article, a pair of arms pivoted respectively to said second pair of links intermediate the ends thereof, a second roller extending between said pair of arms and journaled therein, said second roller being positioned such as to be contacted and moved forwardly by an article being conveyed by said conveyor, means for moving said second roller over a surface of an article being conveyed as said roller is being moved forwardly under the urging of an article being conveyed to wrap said wrapping sheet over said surface of the article toward said first roller.
Claim 5
Independent Claim
99 words
An apparatus for wrapping a sheet about an article moving in one direction comprising a frame, a first arm pivoted at one end to said frame, a second arm pivoted at one end to said first arm intermediate the length of said first arm, a first sheet-smoothing and wrapping roller journaled in the other end of said first arm for wrapping a sheet over said article, and a second sheet-smoothing and wrapping roller journaled in the other end of said second arm for wrapping said sheet over said article in a direction opposed to that of said first roller.
Claim 6
Independent Claim
99 words
An apparatus for wrapping a sheet about an article moving in one direction comprising a frame, a first arm pivoted at one end to said frame, a second arm pivoted at one end to said first arm intermediate the length of said first arm, a first sheet-smoothing and wrapping roller journaled in the other end of said first arm for wrapping a sheet over said article, and a second sheet-smoothing and wrapping roller journaled in the other end of said second arm for wrapping said sheet over said article in a direction opposed to that of said first roller.
Claim 7
Independent Claim
174 words
An apparatus for wrapping a sheet about an article moving in one direction comprising a frame, a conveyor on said frame for moving articles forwardly in said one direction, a first pair of arms pivoted to said frame, a second pair of arms pivoted respectively to said first pair of arms intermediate the ends of said first pair of arms, a first wrapping roller extending between said first pair of arms and journaled therein for wrapping a sheet over said article, a second roller extending between said second pair of arms and journaled therein for wrapping a sheet over said article in a direction toward said first roller, said second roller being positioned such as to be contacted by an article being conveyed by said conveyor whereby forward movement of said article causes movement of said rollers over the surface of said article, and means to alter the length of said first pair of arms during operation of the apparatus whereby said first roller follows the contour of said article during the wrapping thereof.
