Abstract
Abstract An apparatus for dispensing predetermined amounts of lining material into cap shells, particularly of the deeply recessed type, includes a conveyor including a passage for conveying cap shells at predetermined speeds, an extruder provided above and along the shell-conveying passage for extruding predetermined quantities of a lining material through a discharge passage, a blade fitted adjacent to the exit end of the discharge passage and rotatably across it for cutting the lining material, and a drive for rotating the blade in response to the conveying of the cap shells. The drive is adapted to rotate the blade at a non-uniform speed in response to the speed of shell conveyance so that its speed gradually decreases as the exterior end of the blade in its radial direction approaches the shell-conveying passage, and gradually increases as it departs from it, whereby collision between the tip of the blade and the cap shells can be completely avoided.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
An apparatus for dispensing predetermined amounts of lining material into cap shells, said apparatus comprising: conveyor means including a passage for conveying cap shells at predetermined speeds; extruder means provided above and along the shell-conveying passage for extruding a predetermined quantity of a lining material through a discharge passage into each cap shell; a blade positioned adjacent the exit end of said discharge passage and adapted to rotate across said exit end for cutting said lining material into said predetermined quantity; and drive means for rotating said blade at a non-uniform speed in response to the speed of conveyance of said cap shells such that the speed of said blade gradually decreases as the exterior end of said blade in its radial direction approaches said shell-conveying passage, and such that the speed of said blade gradually increases as said exterior blade end moves away from said shell-conveying passage.
Claim 2
Independent Claim
148 words
An apparatus for dispensing predetermined amounts of lining material into cap shells, said apparatus comprising: conveyor means including a passage for conveying cap shells at predetermined speeds; extruder means provided above and along the shell-conveying passage for extruding a predetermined quantity of a lining material through a discharge passage into each cap shell; a blade positioned adjacent the exit end of said discharge passage and adapted to rotate across said exit end for cutting said lining material into said predetermined quantity; and drive means for rotating said blade at a non-uniform speed in response to the speed of conveyance of said cap shells such that the speed of said blade gradually decreases as the exterior end of said blade in its radial direction approaches said shell-conveying passage, and such that the speed of said blade gradually increases as said exterior blade end moves away from said shell-conveying passage.
Claim 3
Dependent Claim
63 words
An apparatus as claimed in claim 1, wherein said drive means comprises means for rotating said blade at a non-uniform speed such that a component in the cap shell-conveying direction of the moving speed of said exterior end of said blade becomes substantially equal to the moving speed of said cap shell when said exterior end of said blade approaches said cap shell.
Claim 4
Dependent Claim
68 words
An apparatus as claimed in claim 1, wherein said drive means comprises means for rotating said blade at a non-uniform speed such that a component in the cap shell-conveying direction of the moving speed of said exterior end of said blade becomes substantially equal to the moving speed of said cap shell when said exterior end of said blade moves toward and away from said cap shell-conveying passage.
Claim 5
Dependent Claim
47 words
An apparatus as claimed in claim 1, wherein said drive means comprises a drive motor, a first non-circular gear connected to a rotating output shaft of said drive motor, and a second non-circular gear connected to said blade and in meshing engagement with said first non-circular gear.
