The device can automatically detect the height of the material, and achieves high efficiency.

A method for implementing a correct winding of a wire on a spool. The method is characterized in that it comprises a step for calculating the angular speed of a motor displacing a wire dispensing device according to the wire winding pitch and according to the pulling error, detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible valley error, or of a possible peak error. Furthermore, if during the spool winding a valley error or a peak error is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or of skipping the peak.

A needle grab for handling workpieces has a bar-shaped longitudinally elongated housing having a longitudinally extending face and first and second longitudinally spaced guides defining respective first and second transverse directions that cross each other. First and second holders are transversely slidable in the first and second guides in the respective directions and carry respective first and second sets of at least three first and second grab needles movable with the respective holders relative to the face between a release position recessed behind the face and a gripping position projecting from the face in the first and second directions. A single servomotor is mounted on the housing and is connected via a gear train to both of the holders for synchronously moving same to displace the first and second sets of needles synchronously in the respective first and second directions.

To provide a transfer apparatus correcting a curl of a card efficiently while preventing the card from deteriorating, a printing apparatus includes a transfer section transferring a transfer surface of a transfer film to the card, a rotating unit reversing the front side and back side of the card in two-sided transfer, a decurl mechanism correcting a curl of the card with the transfer surface transferred in the transfer section, and a control section controlling the decurl mechanism. The control section controls the decurl mechanism such that a correction amount for the card with the transfer surface transferred to one surface in two-sided transfer is smaller than a correction amount for the card in one-sided transfer, and that the total sum of correction amounts for respective surfaces of the card in two-sided transfer is smaller than the correction amount for the card in one-sided transfer.

A postprocessing device includes a pair of folding rollers, a folding blade, a transport device, a roller driver, a blade driver, and a drive controller. The drive controller selectively performs one of a first rotation control, including controlling the roller driver to keep rotation speed of the pair of folding rollers constant, while the folding blade is moving away from a nip region, and a second rotation control, including controlling the roller driver to stop the rotation or slow down the rotation speed of the pair of folding rollers, while a tip portion of the folding blade is being withdrawn from a folded portion of a sheaf of sheets folded, and to restore the rotation speed of the pair of folding rollers to original rotation speed, after the tip portion of the folding blade has been removed from the folded portion of the sheaf of sheets folded.

Disclosed is a method and an apparatus for supplying, staging, and/or handling, and/or for replacing rolls (12, 20) with flat material and/or film material wound thereonto and serving as packaging material (22) for packaging piece goods, bundles, or the like sets of articles. Depleted rolls (20) are removed from at least one installation position (EB1, EB2) of a packaging machine (14), and new rolls (12) are mounted into the particular installation position (EB1, EB2), with new rolls (12) being staged to the packaging machine (14) in a specified feeder device.

Each of the installation positions (EB1, EB2) of the packaging machine (14) includes at least one rotatable receiving mandrel (70) for the rotatable reception and holding of the rolls (12). The at least one receiving mandrel (70) is shiftable in its axial direction upon removing a depleted roll (20) and/or upon mounting of a new roll (12).
