A driving device for a stepping motor includes a motor driving circuit configured to generate a current waveform representing an electrical angle in synchronization with a mechanical angle of the stepping motor, and excite the stepping motor using the current waveform; a memory configured to store a value of the electrical angle; and a controller configured to: when a power supply to the stepping motor and the motor driving circuit is stopped, store a first value of the electrical angle held by the motor driving circuit in the memory; and when the power supply is resumed, replace a value of the electrical angle of the motor driving circuit with the first value while suppressing a rotational operation of the stepping motor.

An interleaving unit, comprising a pair of rolls (1, 2) set alongside one another and counter-rotating and provided with respective first and second folding tools (3, 4; 5, 6) set at a distance from one another along the circumferential development of the respective peripheral surfaces so as to operate in a common point of tangency (Z) on a succession of sheets (7a, 7b) fed between the two rolls, said tools (3, 4; 5, 6) being set on respective mobile cylinder sectors (8, 9, 10, 11) to enable positioning thereof at an adjustable distance apart along the circumferential development of a corresponding roll (1, 2), said interleaving unit comprising means (M1, M2, U) for independently adjusting the speed of rotation of one or more of said sectors according to their angular position in order to reduce or increase the peripheral speed of said sectors with respect to a speed of feed (Vm) of said sheets.

A transfer and dispensing apparatus is disclosed for the conveying and separation of packaging material, cushions or pillows when needed by the operator. When a packer working over a conveyor receives a box that requires void fill, an operating switch such as a foot pedal is depressed to dispense pillows from the apparatus and into the box in a connected strip. When the operating switch is released, the apparatus stops dispensing pillows, separates the continuous strip of pillows along a transverse perforation in the strip, and ejects the end of the separated segment. The packer can then complete packing the box by placing the severed end of the pillows into the box, advance to the next box, and repeat the process. The transfer and dispensing apparatus may be positioned in any convenient location including adjacent to, above or attached to the inflation device.

Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.

A unit for thermosetting printed fabrics, comprising: a heated roller rotating about a rotation axis and having a cylindrical outer surface, at least one fabric guiding element having an inner wall facing the cylindrical outer surface of the heated roller and defining a gap with the cylindrical outer surface of the heated roller, for passing the fabric wherein said fabric guiding element is carried by an adjusting device rotatable about said rotation axis to adjust the angular position of said guiding element about said rotation axis.

The present disclosure relates to apparatuses and methods for making tampons including primary and secondary absorbent members. During assembly, primary absorbent members, a continuous length of secondary absorbent members, and a continuous cord are advanced in a machine direction. Leading edges of the primary absorbent members are separated from each other in the machine direction by a pitch distance. Discrete secondary absorbent members are cut from the continuous length of secondary absorbent members. Leading edges of the discrete secondary absorbent members are also separated from each other in the machine direction by the pitch distance. The continuous cord is positioned on the secondary absorbent members. And a secondary absorbent member is positioned in contact with a primary absorbent member. A thread is combined with the continuous cord, the secondary absorbent member, and the primary absorbent member.
