Abstract
Abstract There is provided an improved method and apparatus for assembling inner liners with a connector of the type open at one end and having a plurality of inwardly extending protuberances. In accordance with the method, the liner is inserted into the connector in generally U-shape with the ends thereof projecting from the open end of the connector. An elastic band is positioned at the open end of the connector and expanded over the connector to fit over the surface of the connector. The expanded band is then moved over the folded ends of the liner onto the outer surface of the connector thereby securing the ends of the liner with the elastic band. An apparatus is provided for carrying out this method.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
An improved method of assembling an inneR lining formed of a thin strip of ribbon with a connector of the type open at one end and having a plurality of inwardly extending protuberances, said method including the step of inserting the lining in general Ushape with the ends thereof projecting from the open end of the connector, folding the open projecting ends of said lining over the ends of the connector along the outer surface thereof, and securing the ends of the lining with an elastic band.
Claim 2
Dependent Claim
87 words
An improved method of assembling an inneR lining formed of a thin strip of ribbon with a connector of the type open at one end and having a plurality of inwardly extending protuberances, said method including the step of inserting the lining in general Ushape with the ends thereof projecting from the open end of the connector, folding the open projecting ends of said lining over the ends of the connector along the outer surface thereof, and securing the ends of the lining with an elastic band.
Claim 3
Independent Claim
120 words
A method of assembling an inner liner formed of a thin strip of ribbon with a connector of the type open at one end and having a plurality of inwardly extending protuberances, said method including the steps of inserting the liner into the connector in generally U-shape with the ends thereof projecting from the open end of the connector; positioning an elastic band at the open end of the connector and expanding the band to fit over the outer surface of the connector, and folding the open projecting ends of the liner over the ends of the connector and moving the band over the folded ends of the liner thereby securing the ends of the liner with the elastic band.
Claim 4
Independent Claim
120 words
A method of assembling an inner liner formed of a thin strip of ribbon with a connector of the type open at one end and having a plurality of inwardly extending protuberances, said method including the steps of inserting the liner into the connector in generally U-shape with the ends thereof projecting from the open end of the connector; positioning an elastic band at the open end of the connector and expanding the band to fit over the outer surface of the connector, and folding the open projecting ends of the liner over the ends of the connector and moving the band over the folded ends of the liner thereby securing the ends of the liner with the elastic band.
Claim 5
Dependent Claim
41 words
The method as set forth in claim 2 wherein the inserting step includes positioning a liner across the open end of said connector, engaging said liner at its center with a blade, and driving said blade and liner into said connector.
Claim 6
Dependent Claim
30 words
The method as set forth in claim 3 wherein said engaging step includes piercing said liner with a needle-like point on said blade to prevent slippage during the insertion procedure.
Claim 7
Dependent Claim
72 words
The method as set forth in claim 3 wherein said positioning step includes supporting the free end of a continuous supply of a thin strip of ribbon by a vacuum support, gripping such free end of the supply of ribbon with a movable vacuum gripper across the open end of a connector so as to position a length of ribbon strip for forming a liner across the open end of a connector.
Claim 8
Dependent Claim
33 words
The method as set forth in claim 5 wherein simultaneously with said inserting step there is providing cutting of the liner from the continuous supply of thin strip of ribbon at proper length.
Claim 9
Dependent Claim
48 words
The method as set forth in claim 2 wherein the positioning of the elastic band is between the projecting open ends of the liner, and the moving step comprises pushing the expanded band into the end of the connector simultaneously folding the open projecting ends of the liner.
Claim 10
Independent Claim
125 words
An apparatus for assembling an inner liner formed of a thin strip of ribbon with a connector of the type open at one end and having a plurality of inwardly extending protuberances, said apparatus including: means for inserting the liner into the connector in generally U-shape with the ends thereof projecting from the open end of the connector; means for positioning an elastic band at the open end of the connector and expanding the band to fit over the outer surface of the connector; and means for folding the open projecting ends of the liner over the ends of the connector and means for pushing the band over the folded ends of the liner thereby securing the ends of the liner with the elastic band.
Claim 11
Independent Claim
125 words
An apparatus for assembling an inner liner formed of a thin strip of ribbon with a connector of the type open at one end and having a plurality of inwardly extending protuberances, said apparatus including: means for inserting the liner into the connector in generally U-shape with the ends thereof projecting from the open end of the connector; means for positioning an elastic band at the open end of the connector and expanding the band to fit over the outer surface of the connector; and means for folding the open projecting ends of the liner over the ends of the connector and means for pushing the band over the folded ends of the liner thereby securing the ends of the liner with the elastic band.
