The paper winding machine has a large support roller (1) which fits against the roll (3) of paper. Two smaller support rollers (4, 5) are mounted above the large roller, on either side of it, so that they form a nip with the paper roll.

Tractionless planishing machine has at least the first five rollers from the inlet with an inter-axis relationship on a radius identical to that of a conventional planishing machine and at least the last five rollers from the inlet with an inter-axis relationship on a radius close to that of a bending machine. The inter-axis relationship between the intermediate rollers is advantageously augmented. An independent claim is also included for: the planishing of metal strip using this planishing machine.

The device with a housing and several rollers, circular-cylindrical drums and the like, the axles of which are parallel and which are mounted between two walls, in particular for forming a strip, which can be formed at elevated temperatures, as it passes through on the surface of a rotating drum, is characterized in that one of the walls can be pivoted open in order to expose the rollers, drums and the like and one of the walls is fastened by way of one or more hinges to a component which can be displaced parallel to the axles, and in that a locking element is provided on the other side, which locking element acts on the wall, fixes or releases the latter and is likewise attached to a component which can be displaced parallel to the axles.

The fittings for a cleaning roller with textile or plastics filaments or strips (4) and the like, in a car wash assembly, have axial sections as carrier baskets (8) butting against each other on the roller shaft. The axial ends of each basket section have flanges (14), which are locked together by pins (16) through a number of openings (15) in a 360[deg] distribution around the flanges. The cleaning filaments or strips are held in place by a holder (9) in a release mounting.

The invention relates to a roller ( 21 ) from a refractory material, for example in vitreous silica, for transporting a flat article provided at its end with a new arrangement for rotationally driving it as well as to an assembly of such a roller and its driving device. This roller ( 21 ) comprises an external surface ( 2 ), an inner surface ( 5 ) and two side surfaces ( 12 ), at least one side surface having indentations ( 22 ) parallel to the roller axis ( 3 ) and spaced apart from the external ( 2 ) and inner surface ( 5 ) for receiving rotationally driving pins ( 8 ), it is characterized in that at least one of the indentations ( 22 ) of the roller is provided with a metal jacket ( 24 ). The invention permits to avoid the breakage of the roller around the driving indentations.

A calibrating basket for calibrating the extruded plastic tube has guiding bows(2) carrying guide rolls(4) for the tubular film. The guide rolls are formed by anti friction roller bearings. Each bearing has an inner ring(6) fixed to a guide bow(2) and a rotatable outer ring(7) supported via rollers(8) on the inner ring. An anti-adhesion coating covers the surface(11) of the outer ring. A gap exists between rollers on the guide bow.

A conveying device ( 1 ) which is particular in that the conveying device comprises a plurality of conveying elements ( 2 ), where each conveying element ( 2 ) comprises a chain box element ( 4 ) in which at least one transport roller ( 3 ) is rotatably fixed such that rollers ( 3 ) arranged in adjacent conveying elements ( 2 ) define the conveying device transport plane, and that chain box elements ( 4 ) of adjacent conveying elements are interconnected in such a way that one conveying element may articulate in relation to adjacent conveying elements, and that at least some of the chain box elements in the conveying device comprise drive elements directly engaging and rotating the transport rollers ( 3 ).

The invention concerns a roller (R), used in continuous product heating furnaces for handling and conveying steel products and in particular slabs. The associated apparatus includes a cooled central shaft (1), cooled by a liquid. On the shaft are mounted a plurality of discs (2), for supporting the products (3) to be transported, arranged perpendicularly to the longitudinal geometrical axis of the roller (R), spaced apart along the axis of the roller (R) and separated by an insulating sleeve (4). The insulating sleeve (4) is maintained at each longitudinal end by at least one cold component (5) secured to the shaft (1) and cooled by the shaft, with axial play (Ja) between the sleeve (4) and the shaft (1) such that possible sagging of the shaft (1) may occur in use without causing substantial mechanical stress on the insulating sleeve (4) and the heat transferred from the sleeve (4) to the shaft (1), and from the discs (2) to the sleeve (4) is limited.

The absorbent paper roll contains layers of cellulose wadding sheets (1a, 1b), each with at least one ply having a weight of between 10 and 40 g/sq m. The sheets have thicker zones (4) that are separated for at least 90 per cent of their periphery by thinner zones (5), and in the outer layers of the roll the thicker zones are positioned so that they at least partially overlap one another, creating a difference in height (H) on at least the outside of the roll. The thicker zones of the paper are produced by micro-embossing, forming projecting areas with at least 30 points per sq cm, with the point having areas of between 0.03 and 2 sq mm at their tips. The difference in thickness between the thicker and thinner zones of the paper is at least 10 per cent and preferably at least 20 per cent.

A device for forming fabric folds in a machine for treating fabrics, particularly a folded fabric steaming machine, comprising a fabric treatment chamber (1), equipped with an inlet (6) and an outlet (7) of the fabric and a chain conveyor (T) for advancing the fabric in said chamber (1). The conveyor comprises rods (20), whereon folds are formed and supported, which are mounted on the conveyor by means of arms (24). The device provides two shaped plates (30) whereon the arms (24) supporting the rods (20) slide. When the fabric advances, the arms (24) are overturned by lifting the rods (20), from a condition hung to the transport chains in the ascending tract (18) thereof, to a condition resting on rails (28) arranged above the active branches (16) of said chains.
