Abstract
Abstract A closure band and a method for interconnecting the overlapping ends of the band and an apparatus for making the connection in which incisions are formed laterally into the opposite edges of the superimposed band ends to form tabs along the band edges. The tabs are bent out of the plane of the band ends so that the tabs on the edges of one band are disposed within the tab spaces of the other band end. The tabs are advantageously formed so as to be wider at the outer free ends than the spaces on the other band ends on which the tabs are disposed, whereby the band ends are fixedly interconnected in tension transmitting relation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
209 words
An apparatus for connecting the overlapping ends of a closure band to secure the band ends together in tension transmitting relation which comprises; a pair of cutting devices adapted to receive therebetween the band ends in superposed face to face relation, said cutting devices being operable upon movement toward each other to cut pairs of lateral incisions into the edges of the band ends to form tabs on the band edges between the pairs of said incisions, said cutting devices also bending the tabs out of the planes of the bands to dispose the tabs on the edges of one band end in the space between a respective pair of incisions in the edges of the other band end, said cutting devices comprising first movable cutting blades engaging one band end at opposite sides of the tab to be formed therein and a second cutting blade engaging the other band end in the region of the tab, said second cutting blade having a nonmovable part engaging the center region of the tab and movable parts on each side of the nonmovable part engaging the side regions of the tab, and means for controlling the movement of said first cutting blades and the movable parts of said second cutting blade.
Claim 2
Independent Claim
209 words
An apparatus for connecting the overlapping ends of a closure band to secure the band ends together in tension transmitting relation which comprises; a pair of cutting devices adapted to receive therebetween the band ends in superposed face to face relation, said cutting devices being operable upon movement toward each other to cut pairs of lateral incisions into the edges of the band ends to form tabs on the band edges between the pairs of said incisions, said cutting devices also bending the tabs out of the planes of the bands to dispose the tabs on the edges of one band end in the space between a respective pair of incisions in the edges of the other band end, said cutting devices comprising first movable cutting blades engaging one band end at opposite sides of the tab to be formed therein and a second cutting blade engaging the other band end in the region of the tab, said second cutting blade having a nonmovable part engaging the center region of the tab and movable parts on each side of the nonmovable part engaging the side regions of the tab, and means for controlling the movement of said first cutting blades and the movable parts of said second cutting blade.
Claim 3
Dependent Claim
65 words
An apparatus according to claim 1 in which said parts of said second cutting blade are in the form of discs, bolt means extending through said discs and rigidly supporting said nonmovable part, said movable parts being pivotal on one of said bolt means and comprising abutment means cooperating with another of said bolt means to limit the amount of movement of said movable parts.
Claim 4
Dependent Claim
49 words
An apparatus according to claim 2 which includes an actuator connected to said first cutting blades to move the first cutting blades toward the second cutting blade, said actuator being engageable with said movable parts for movement thereof toward said first cutting blades following the cutting of said incisions.
Claim 5
Dependent Claim
43 words
An apparatus according to claim 3 in which said actuator is connected to said first cutting blades by links which extend substantially perpendicularly to the direction of movement of said actuator when said actuator engages said movable parts of said second cutting blade.
Claim 6
Independent Claim
193 words
An apparatus for connecting the overlapping ends of a closure band to secure the band ends together in tension transmitting relation which comprises; a pair of cutting devices adapted to receive therebetween the band ends in superposed face to face relation, said cutting devices being operable upon movement toward each other to cut pairs of lateral incisions into the edges of the band ends to form tabs on the band edges between the pairs of said incisions, said cutting devices also bending the tabs out of the planes of the bands to dispose the tabs on the edges of one band end in the space between a respective pair of incisions in the edges of the other band end, said cutting devices comprising a blade on each of the upper and lower sides of a tab region and further cutting blades at the sides of said first mentioned blades, said further blades each comprising a pair of plates and spring means acting therebetween to permit the plates to move toward each other under pressure, said first mentioned blades including means for notching or upsetting the free outer ends of the tabs formed thereby.
Claim 7
Independent Claim
193 words
An apparatus for connecting the overlapping ends of a closure band to secure the band ends together in tension transmitting relation which comprises; a pair of cutting devices adapted to receive therebetween the band ends in superposed face to face relation, said cutting devices being operable upon movement toward each other to cut pairs of lateral incisions into the edges of the band ends to form tabs on the band edges between the pairs of said incisions, said cutting devices also bending the tabs out of the planes of the bands to dispose the tabs on the edges of one band end in the space between a respective pair of incisions in the edges of the other band end, said cutting devices comprising a blade on each of the upper and lower sides of a tab region and further cutting blades at the sides of said first mentioned blades, said further blades each comprising a pair of plates and spring means acting therebetween to permit the plates to move toward each other under pressure, said first mentioned blades including means for notching or upsetting the free outer ends of the tabs formed thereby.
Claim 8
Dependent Claim
15 words
An apparatus according to claim 5 in which said spring means comprise resilient O-ring means.
