Claim 3

Apparatus for adhering a tin-tie of extended length, moderate width and slight thickness to a surface with which it is to coact, comprising A. means for deforming the transverse section of the tin-tie into a configuration having a convex arcuate surface; B. means for confining the edges of the tin-tie to maintain its arcuate configuration while adhesive is applied longitudinally to the central portion of the convex arcuate surface; and C. means for conveying the convex arcuate surface, with its edges still confined, into progressive engagement with the surface with which it is to coact.

Claim 4

Apparatus for adhering a tin-tie of extended length, moderate width and slight thickness to a surface with which it is to coact, comprising A. means for deforming the transverse section of the tin-tie into a configuration having a convex arcuate surface; B. means for confining the edges of the tin-tie to maintain its arcuate configuration while adhesive is applied longitudinally to the central portion of the convex arcuate surface; and C. means for conveying the convex arcuate surface, with its edges still confined, into progressive engagement with the surface with which it is to coact.

Claim 5

Apparatus for adhering a tin-tie of extended length, moderate width and slight thickness to a continuously moving surface with which it is to coact, comprising A. means for deforming the transverse section of the tin-tie into arcuate form; B. means for confining the edges of the tin-tie to maintain its arcuate form and for moving successive longitudinal elements of the edge-confined tin-tie along a path which

Claim 6

Apparatus for adhering a tin-tie of extended length, moderate width and slight thickness to a continuously moving surface with which it is to coact, comprising A. means for deforming the transverse section of the tin-tie into arcuate form; B. means for confining the edges of the tin-tie to maintain its arcuate form and for moving successive longitudinal elements of the edge-confined tin-tie along a path which

Claim 7

thereafter approaches tangentially the path of movement of the surface with which the tin-tie is to coact, whereby that surface is progressively bonded to the adhesive-bearing surface of the tin-tie.

Claim 8

thereafter approaches tangentially the path of movement of the surface with which the tin-tie is to coact, whereby that surface is progressively bonded to the adhesive-bearing surface of the tin-tie.

Claim 9

Apparatus accordinG to claim 2 in which the said path is curvilinear and of such form that the convex surface of the tin-tie is presented in a down-oriented direction to the source of adhesive and in an up-oriented direction to the surface with which it is to coact.

Claim 10

Apparatus for attaching tin-tie strips to a succession of containers comprising, in combination A. a rotatable support member having a closed continuous periphery and an annular groove formed in and coextensive with that periphery; B. means for rotating the support member; C. means for arcuately bending the transverse section of a tintie strip wider than said groove and for feeding the bent strip lengthwise into said groove for temporary retention therein with its convex arcuate surface outwardly directed; D. applicator means mounted adjacent the periphery of said member for applying an adhesive to the outwardly directed surface of a strip retained in said groove during rotation of the member relative to said applicator means; E. means for advancing a container along a path tangent to the periphery of said member; and F. means for simultaneously disengaging an adhesive-bearing strip from said groove and pressing the adhesive-bearing surface of the strip into contact with a container as the latter is moved tangent to the periphery of said member.

Claim 11

Apparatus for attaching tin-tie strips to a succession of containers comprising, in combination A. a rotatable support member having a closed continuous periphery and an annular groove formed in and coextensive with that periphery; B. means for rotating the support member; C. means for arcuately bending the transverse section of a tintie strip wider than said groove and for feeding the bent strip lengthwise into said groove for temporary retention therein with its convex arcuate surface outwardly directed; D. applicator means mounted adjacent the periphery of said member for applying an adhesive to the outwardly directed surface of a strip retained in said groove during rotation of the member relative to said applicator means; E. means for advancing a container along a path tangent to the periphery of said member; and F. means for simultaneously disengaging an adhesive-bearing strip from said groove and pressing the adhesive-bearing surface of the strip into contact with a container as the latter is moved tangent to the periphery of said member.

Claim 12

Apparatus according to claim 4 in which the side walls of said groove are undercut to facilitate retention of a strip therein.

Claim 13

Apparatus according to claim 4 wherein the last-mentioned means include a stripping element extending tangent to the periphery of said member into said groove in a direction opposed to the direction of rotation of the member for guiding a strip from said groove into contact with the material of a container.

Claim 14

Apparatus according to claim 6 which further includes a backing member for pressing the container material against the strip during and after the action of the stripping element.

Claim 15

Apparatus according to claim 7 wherein said backing member comprises an endless belt and further including means for advancing said endless belt at the same linear speed and in the same direction as the strip and container material.

Claim 16

Apparatus according to claim 8 further including a second endless belt supported for co-directional movement in juxtaposition with the first-mentioned belt for gripping the container material and strip between said belts.

Claim 17

Apparatus according to claim 9 wherein said belts are formed of a heat conductive material for atemperating the adhesive to promote firm adherence of the strip to the container material.

Claim 18

Apparatus according to claim 4 which further includes means for cutting a strip to desired length during introduction of the strip into said groove.
