Abstract
The object of the present invention is to recondition cardboard or similar tubes with deformed parts, notably at the ends, whilst avoiding the usual milling techniques and without removing any material. The deformed parts of each tube (1) are recalibrated to their initial thickness by being rolled between pairs of rollers (15, 20), of which at least one is driven in rotation. The tube (1) is then supported only by the rollers. Each internal roller (20) can be mounted on a movable support (18) which brings it into its working position in the tube. Application for the reconditioning of tubes serving as supports for textile yarn reels.
Claims11
A device, for reconditioning tubes with deformed parts, comprising:
- a series of treatment stations and conveying means to convey the tubes one after the other to the treatment stations, wherein the treatment stations comprise at least one rolling station (7) comprising
- at least one internal roller (20, 27) and at least one external roller (15, 26), the external roller being connected to a rotational drive mechanism (12-14) and the internal roller being rotatably mounted to a movable support (18,28) for free rotation on the movable support (18,28);
- wherein an actuator (22) is connected to the movable support (18, 28) for moving the movable support and thereby moving the internal roller (20, 27) between:
- (i) a withdrawn position where the internal roller (20, 27) is separated from the external roller (15, 26) and does not engage the tubes on the conveying means (4);
- and
- (ii) a working position where the internal roller (20, 27) is inserted in an end of one of the tubes, whereby the one of the tubes is lifted and supported by the internal roller (20, 27) above the conveying means (4) during rolling, and a wall of the one of the tubes is pressed between the internal roller (20, 27) and the external roller (15, 26).
