Abstract
Abstract This invention relates to supply means for web or ribbon feed machines where the ribbon is unreeled from a storage supply means such as a reel in substantially continuous motion, and is fed through the mechanism of the machine by an intermittent motion. The purpose of the invention is to provide mechanical filter means cooperating with a booster assist drive connected to the main drive of the device to translate the intermittent motion of the feed of the machine to a smooth, continuous motion at the supply means or reel for the ribbon. In the preferred form of the invention, the booster is a cylindrical roll in the ribbon pathway adapted to frictionally engage the ribbon, and the mechanical filter comprises a ribbon holding means, or brake, to prevent the ribbon from reversing its motion, and a coercing member, such as a tension member, spring urged against the ribbon within the ribbon pathway, between the ribbon holding means and the booster roll, as will be more fully described and claimed hereinbelow.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
203 words
Supply means for a feed device for a web, ribbon, or the like, said device incluDing a main frame, a ribbon in a ribbon pathway having a first end and a second end, and intermittent feed means to feed the ribbon at the first end of the ribbon pathway; with said supply means comprising ribbon storage means at the second end of said ribbon pathway, mechanical filter means associated with said ribbon pathway between said ribbon storage means and said intermittent feed means, said mechanical filter means converting the intermittent motion of the ribbon at the feed means into continuous motion of the ribbon where it leaves the ribbon storage means; and booster means positioned along said ribbon pathway between said ribbon storage means and at least a portion of said mechanical filter means, said booster means comprising friction drive means including a moving friction surface portion normally positioned to contact the ribbon when placed in tension by the feed means, said moving friction surface moving at a speed greater than the speed of the ribbon; the contact between the ribbon and the moving friction surface being provided by pull of the ribbon by the feed means and pressure of the filter means.
Claim 2
Dependent Claim
203 words
Supply means for a feed device for a web, ribbon, or the like, said device incluDing a main frame, a ribbon in a ribbon pathway having a first end and a second end, and intermittent feed means to feed the ribbon at the first end of the ribbon pathway; with said supply means comprising ribbon storage means at the second end of said ribbon pathway, mechanical filter means associated with said ribbon pathway between said ribbon storage means and said intermittent feed means, said mechanical filter means converting the intermittent motion of the ribbon at the feed means into continuous motion of the ribbon where it leaves the ribbon storage means; and booster means positioned along said ribbon pathway between said ribbon storage means and at least a portion of said mechanical filter means, said booster means comprising friction drive means including a moving friction surface portion normally positioned to contact the ribbon when placed in tension by the feed means, said moving friction surface moving at a speed greater than the speed of the ribbon; the contact between the ribbon and the moving friction surface being provided by pull of the ribbon by the feed means and pressure of the filter means.
Claim 3
Dependent Claim
36 words
Supply means for intermittent feed means as defined in claim 1, including ribbon holding means associated with the ribbon pathway positioned between the intermittent feed means and at least a portion of the mechanical filter means.
Claim 4
Dependent Claim
49 words
Supply means as defined in claim 1, in which the intermittent feed means and the friction drive means are driven by main drive means of the device with the speed of said friction surface being greater than the speed of the ribbon as it leaves the ribbon storage means.
Claim 5
Dependent Claim
49 words
Supply means for intermittent feed means as defined in claim 2, in which the ribbon holding means is movably positioned to apply friction to the web, being movable with relation to the web to apply less friction in a forward direction of web motion than in a backward direction.
Claim 6
Dependent Claim
27 words
Supply means as defined in claim 4, in which the friction drive means is substantially cylindrical in form with said friction surface portion being the circumference thereof.
Claim 7
Dependent Claim
33 words
Supply means as defined in claim 5, in which the mechanical filter means comprises tension member means mounted in association with the ribbon pathway by means of a mounting which comprises elastic means.
Claim 8
Dependent Claim
22 words
The supply means as defined in claim 6, in which the tension member means includes a body portion comprising a curved surface.
Claim 9
Dependent Claim
23 words
The supply means as defined in claim 6, in which the elastic means of the tension member means comprises at least one spring.
Claim 10
Dependent Claim
57 words
The supply means as defined in claim 6, in which the ribbon pathway runs from the ribbon storage means around a portion of the circumference of the friction surface portion, thence toward said tension member means of said mechanical filter means, thence along a surface of said tension member means, and thence to said intermittent feed means.
Claim 11
Dependent Claim
33 words
The supply means as defined in claim 9, including ribbon holding means associated with the ribbon pathway positioned between the intermittent feed means and the tension member means of the mechanical filter means.
Claim 12
Dependent Claim
52 words
The supply means as defined in claim 10, in which the ribbon holding means is friction activated and comprises at least one movable element adapted to generate friction against the ribbon during the forward movement of the ribbon, and generate increased friction against the ribbon on a rearward movement of the ribbon.
