摘要： The present invention relates to a transfer device that can feed a work in a stable condition without applying it any excess loads. The transfer device for feeding a tape-shaped work to a process stage standing in an upright position, which is placed on one side of the process stage and which includes a supply reel, a take-up reel and a work feeding mechanism. Specifically, the supply reel, around which the work and a protective sheet are wound, is adapted to feed the work and the protective sheet therefrom. The take-up reel is adapted to wind the work and the protective sheet that have been fed from the supply reel, and it is located below the supply reel. The work feeding mechanism is adapted to forward the work from the supply reel to the take-up reel through the process stage.

摘要： A web is threaded in the reeling of a paper or board web, by passing a web tail strip (W) into a reeling nip between a reeling drum (10) and a reel spool (12), on which a web roll is formed. The tail strip (W) is passed into the reeling nip by a suction zone (20) which extends substantially around the entire reeling drum circumference and is (10) in an area where a full-width web runs during reeling, so that the tail strip (w) can be conducted directly along the suction zone (20). The suction zone (20) is placed in the longitudinal direction of the reeling drum (10), i.e. in the width direction of the web.

摘要： A wrapping machine having a pre-stretching device for pre-stretching a film web drawn from film roll before its being wrapped around an object, said pre-stretching device including a first pre-stretching roller and a second pre-stretching roller, which are tractively coupled via power transmission gears. A first deflecting pinch roller has been fitted to be pressed against the first pre-stretching roller to form a first nip for the film web passed between the first deflecting pinch roller and the first pre-stretching roller. A second deflecting pinch roller has been fitted to be pressed against the second pre-stretching roller to form a second nip for the film web passed between the second deflecting pinch roller and the second pre-stretching roller. A lever mechanism moves the first pre-stretching roller between an engagement position and a disengagement position, so that the lever mechanism also moves the first deflecting pinch roller apart from the first pre-stretching roller and simultaneously the second deflecting pinch roller apart from the second pre-stretching roller to allow easier thread-in of the film web end.

摘要： A guiding and braking unit for a material web which passes through a processing machine, such as a machine for the manufacture of packing containers. The unit comprises a roller adapted to a guide cylinder for the web. This roller is manufactured from a material with a high coefficient of friction. The roller is adapted so that it can be swivelled via an arm in a direction transverse to that of the material web to thus follow the material web when it is moved sideways, or axially in relation to the guide cylinder. Each sideways movement, however, because of the suspension of the roller, brings about a lifting of the roller which is continuously counteracted by the pressing of the roller against the cylinder. As a result, the roller is returned automatically to a central position and through friction, carries the material web with it to a central position in relation to the guide cylinder.

摘要： Winding device for metal strips, in which the metal strip is braked between two rollers which are pressed against one another. One of the rollers has a larger angle of wrap for the metal strip of at least 75.degree. and the other roller has a smaller angle of wrap for the metal strip of 45.degree. at maximum. The one roller with the larger wrap includes material on its periphery having a coefficient of friction for the material which is at least 20% lower relative to the braked metal strip than the coefficient of friction of the peripheral material of the other roller with the smaller amount of wrap.

摘要： A tensioner for tensioning individually a number of strips that are being rewound side by side simultaneously. The tensioner includes two shafts rotatably carrying opposed rollers, one pair for each strip. The rollers are separated by friction discs keyed to the shafts, the rollers and friction discs being compressed axially together so a pair of rollers rotates on its shafts only when a predetermined tension is exceeded at the strip passing between them. Sideways movement of strips is prevented by separater discs between the rollers. The shafts are rotated at a speed less than the rewind speed of the strips, to reduce slippage between the rollers and the friction discs.
