Abstract
Abstract A reel system for film and the like includes a pair of film plates or disks mounted on respective horizontal arms of an upright support carrying a pair of turntables drivable by respective electric motors. A payout device is fixed in the middle of one of the disks to controlledly draw the film continuously from the interior of the coil and/or to coil the film on the external periphery of the other disk.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
An apparatus for the supply and takeup of film, comprising a support; a pair of generally horizontal coil-carrying disks mounted rotatably upon said support; respective drive means coupled with said disks for rotating same; a pay-out device received at the center of one of said disks for leading a film band from the inner periphery of a supply coil of film positioned on said one of said disks; means for coiling returning film along the exterior of a takeup coil on the other of said disks; and an arm swingable about the center of one of the disks and provided with idler pulleys each at the height of one of said disks for guiding returning film onto a coil adapted to be formed thereon.
Claim 2
Independent Claim
124 words
An apparatus for the supply and takeup of film, comprising a support; a pair of generally horizontal coil-carrying disks mounted rotatably upon said support; respective drive means coupled with said disks for rotating same; a pay-out device received at the center of one of said disks for leading a film band from the inner periphery of a supply coil of film positioned on said one of said disks; means for coiling returning film along the exterior of a takeup coil on the other of said disks; and an arm swingable about the center of one of the disks and provided with idler pulleys each at the height of one of said disks for guiding returning film onto a coil adapted to be formed thereon.
Claim 3
Dependent Claim
55 words
The apparatus defined in claim 1, further comprising means engaging the returning film and shiftable thereby upon the coiling of the returning film on said takeup coil for controlling at least one of said drive means, said other of said disks being provided with a removable ring-shaped core about which said takeup coil is formed.
Claim 4
Independent Claim
115 words
An apparatus for the supply and takeup of film, comprising a support; a pair of generally horizontal coil-carrying disks mounted rotatably upon said support; respective drive means coupled with said disks for rotating same; a pay-out device received at the center of one of said disks for leading a film band from the inner periphery of a supply coil of film positioned on said one of said disks; means for coiling returning film along the exterior of a takeup coil on the other of said disks; pushbutton control means for functionally switching the drive means of each of said disks; and means for interchangeably positioning said device at the center of any of said disks.
Claim 5
Independent Claim
115 words
An apparatus for the supply and takeup of film, comprising a support; a pair of generally horizontal coil-carrying disks mounted rotatably upon said support; respective drive means coupled with said disks for rotating same; a pay-out device received at the center of one of said disks for leading a film band from the inner periphery of a supply coil of film positioned on said one of said disks; means for coiling returning film along the exterior of a takeup coil on the other of said disks; pushbutton control means for functionally switching the drive means of each of said disks; and means for interchangeably positioning said device at the center of any of said disks.
Claim 6
Dependent Claim
45 words
The apparatus defined in claim 3, further comprising an arm swingable about the center of one of the disks and provided with idler pulleys each at the height of one of said disks for guiding returning film onto a coil adapted to be formed thereon.
Claim 7
Independent Claim
287 words
An apparatus for the supply and takeup of film, comprising: a support; a pair of generally horizontal coil-carrying disks mounted rotatably upon said support; respective drive means coupled with said disks for rotating same: a pay-out device received at the center of one of said disks for leading a film band from the inner periphery of a supply coil of film positioned on said one of said disks; means for coiling returning film along the exterior of a takeup coil on the other of said disks; said support including: an upright column and a base carrying said column, and a plurality of codirectionally extending vertically spaced horizontal arms each provided with one of said disks at the free end of the respective arm, said drive means including: respective motors on said arms drivingly connected with said disks for rotating same, a respective well formed in the center of each of said disks for receiving said device, and means for mounting a core interchangeably on said disks for enabling a takeup coil to be formed thereon; one of said disks being provided with a bar swingable about the center of rotation thereof and extending beyond the peripheries of said disks; a vertical rod mounted on the free end of said bar and extending parallel to a common axis of said disks; respective Idler pulleys rotatably mounted on said rod at substantially the same level as each of said disks for deflecting the returning film to the coil adapted to be formed on the respective disk when it is used to take up the returning film; spring means biasing said bar to maintain the returning film under tension; and switch means for selectively controlling the functions of said disks.
Claim 8
Independent Claim
287 words
An apparatus for the supply and takeup of film, comprising: a support; a pair of generally horizontal coil-carrying disks mounted rotatably upon said support; respective drive means coupled with said disks for rotating same: a pay-out device received at the center of one of said disks for leading a film band from the inner periphery of a supply coil of film positioned on said one of said disks; means for coiling returning film along the exterior of a takeup coil on the other of said disks; said support including: an upright column and a base carrying said column, and a plurality of codirectionally extending vertically spaced horizontal arms each provided with one of said disks at the free end of the respective arm, said drive means including: respective motors on said arms drivingly connected with said disks for rotating same, a respective well formed in the center of each of said disks for receiving said device, and means for mounting a core interchangeably on said disks for enabling a takeup coil to be formed thereon; one of said disks being provided with a bar swingable about the center of rotation thereof and extending beyond the peripheries of said disks; a vertical rod mounted on the free end of said bar and extending parallel to a common axis of said disks; respective Idler pulleys rotatably mounted on said rod at substantially the same level as each of said disks for deflecting the returning film to the coil adapted to be formed on the respective disk when it is used to take up the returning film; spring means biasing said bar to maintain the returning film under tension; and switch means for selectively controlling the functions of said disks.
Claim 9
Dependent Claim
68 words
The apparatus defined in claim 5 wherein three such arms and corresponding disks are provided one above another along said column, said bar being swingably mounted on the intermediate arm, said apparatus further comprising speed-control means selectively connectable with one of said motors through said switch means and operatively connected with said bar for controlllng said one of said motors in accordance with the displacement of said bar.
