Definitions
- Means are therefore required to impart these different required traction conditions to the strip.
- Such means are generally either driving or braking rollers, around which the strip extends over an angle a, as shown in FIG. 1.
- a stationary member is disposed outside the roller and formsa chamber between itself and the roller, a pressure fluid being introduced into said chamber to apply the strip to the roller.
- the object of this invention is to improve these latter known systems.
- a system for driving a strip comprising a roller for receiving strip, a shoe applicable radially toward the roller in the region in which the strip will be received, and means to inject a pressure fluid radially inward the shoe, the system being characterized in that the shoe is slightly movable in a fixed frame by ajack so that when pressure fluid is applied between the shoe and a strip received by theroller, the strip will be applied against the roller with a force equal to that exerted by the jack on the shoe, while contact between the shoe and'the strip will be prevented by the formation of a very thin fluid cushion which will leave only a very small clearance between the shoe and the strip and which will prevent any rubbing of the shoe on the strip.
- pressure fluid is compressed air.
- FIG. 1 is a diagrammatic end elevation of a roller with a strip applied to it.
- FIG. 2 is a vertical section of this embodiment.
- the strip 1 moves in the direction of the arrow and passes successively around a deflector roller 2, and then a drive (or brake) roller 3 and finally a deflector roller 4.
- Reference 9 denotes the frame which supports the bearings forming the axes of rotation of the rollers 2, 3 and 4.
- a jack 7 fed with pressure fluid by the device 8 applies the shoe 5 against the strip 1 in the region where said strip extends around the roller 3.
- a device 6 feeds compressed air to the cavity of the shoe 5 adjacent the strip.
- a valve 11 provides a varying pressure loss between the supply 6 and the shoe 5 so that the rate of flow of the fluid can be reduced. Said flow will be adjusted for a given force of the jack 7 to a value just sufficient to prevent the shoe 5 from rubbing on the strip.
- a system for driving a strip comprising a roller for receiving a strip, a shoe movable radially toward the roller in the region in which the strip is received, and means for injecting compressed air radially inward of said shoe against said strip, a fixed frame movably supporting said shoe, a jack moving said shoe in said frame whereby when compressed air is applied between said shoe and said strip on said roller, said strip is applied against said roller with a force equal to that exerted by said jack on said shoe, the compressed air forming a very thin fluid cushion and providing a very small clearance between said shoe and said strip preventing rubbing of said shoe on said strip.
- said means for injecting pressure fluid between said shoe-and said strip including a valve providing an adjustable pressure loss.
