Abstract
Abstract A mounting means for a pair of nip rollers which comprises at each end of the pair of rollers an external mounting plate and an apertured plate, each roller of the said pair having at each end a spindle mounted in a spindle bearing, the bearings passing through one of the apertured plates and being connected to one of the mounting plates, the bearings connected to one roller being a fixed pair and the bearings connected to the other roller being a movable pair, the movable pair being biassed towards the fixed pair, each apertured plate having an aperture in which one of the fixed bearings is located and an aperture in which one of the movable bearings is located but which is greater in area than the diameter of the movable bearing, each movable bearing being attached to one of the mounting plates by a peg mounted thereon that locates in an aperture that is eccentric with regard to its centre so that the bearing is able to rotate about the peg in a direction towards or away from the fixed bearing, the amount of rotation being limited by the shape of the aperture in the apertured plate in which it is located.

Claim 1
Independent Claim
216 words
In an apparatus which comprises at least one pair of driven nip rollers a mounting means for the said pair of nip rollers which comprises at each end of the pair of rollers an external mounting plate and an apertured plate, each roller of the said pair having at each end a spindle mounted in a spindle bearing, the bearings passing through one of apertured plates and being connected to one of the mounting plates, the bearing connected to one roller being a fixed pair and the bearing connected to the other roller being a movable pair, the movable pair being biassed towards the fixed pair, each apertured plate having an aperture in which one of the fixed bearings is located and an aperture in which one of the movable bearings is located which is greater in area than the diameter of the movable bearing, each movable bearing being connected to one of the mounting plates by a peg mounted thereon which locates in an aperture which is eccentric with regard to its centre so that the bearing is able to rotate about the peg in a direction towards or away from the fixed bearings, the amount of rotation being limited by the shape of the aperture in the apertured plate in which it is located.

In an apparatus which comprises at least one pair of driven nip rollers a mounting means for the said pair of nip rollers which comprises at each end of the pair of rollers an external mounting plate and an apertured plate, each roller of the said pair having at each end a spindle mounted in a spindle bearing, the bearings passing through one of apertured plates and being connected to one of the mounting plates, the bearing connected to one roller being a fixed pair and the bearing connected to the other roller being a movable pair, the movable pair being biassed towards the fixed pair, each apertured plate having an aperture in which one of the fixed bearings is located and an aperture in which one of the movable bearings is located which is greater in area than the diameter of the movable bearing, each movable bearing being connected to one of the mounting plates by a peg mounted thereon which locates in an aperture which is eccentric with regard to its centre so that the bearing is able to rotate about the peg in a direction towards or away from the fixed bearings, the amount of rotation being limited by the shape of the aperture in the apertured plate in which it is located.
Claim 3
Dependent Claim
13 words
An apparatus according to claim 1 wherein the movable bearings are circular bearings.
Claim 4
Dependent Claim
34 words
An apparatus according to claim 2 wherein the aperture in which the circular movable bearings are located are circular, the diameter of these apertures being greater than the diameter of the movable circular bearings.
Claim 5
Dependent Claim
13 words
An apparatus according to claim 3 wherein the fixed bearings are circular bearings.
Claim 6
Dependent Claim
30 words
An apparatus according to claim 4 wherein the diameter of the apertures in which the fixed bearings are located is not substantially greater than the diameter of the circular bearing.
Claim 7
Dependent Claim
24 words
An apparatus according to claim 5 wherein the fixed bearings are connected to one of the mounting plates by a peg which locates therein.
Claim 8
Dependent Claim
23 words
An apparatus according to claim 6 wherein the pegs locate in the bearings eccentrically with regard to the centre of the circular bearing.
Claim 9
Dependent Claim
18 words
An apparatus according to claim 1 wherein the movable bearings are biassed towards the fixed bearings by gravity.
Claim 10
Dependent Claim
33 words
An apparatus according to claim 1 wherein movable bearings are biassed towards the fixed bearings by means of spring clips or bands of rubber or synthetic material which encircle both pairs of bearings.
Claim 11
Dependent Claim
33 words
An apparatus according to claim 1 wherein the two apertured plates form part of the outer cover of the apparatus and the mounting plates are small external plates attached to the apertured plates.
