A packaging apparatus for packaging objects, in particular for packaging food portions, having a conveying device (10) for transporting a continuous web of a first packaging material (12), in particular of a bottom film, in a transport direction (TR); and having a feed device (14) for feeding a continuous web of a second packaging material (16), in particular of a top film, in the transport direction (TR), wherein the conveying device (10) comprises a first reception shaft (18) for receiving a first supply roll (20) of the first packaging material (12) and the feed device (14) comprises a second reception shaft (22) for receiving a second supply roll (24) of the second packaging material (16); wherein the first reception shaft (18) can be driven by means of a first drive motor (26) to carry out a rotational movement; and/or wherein the second reception shaft (22) can be driven by means of a second drive motor (28) to carry out a rotational movement, with the first and/or second drive motor (26, 28) in particular being a servomotor or servomotors.

An accumulation device is provided with a loading unit, a tensioning unit, an accumulation unit, and unloading unit and a controller. The tensioning unit comprises multiple fixed rollers capable of rolling, and movable rollers capable of rolling and arranged so as to be capable of moving with respect to the fixed rollers. Substrates are conveyed so as to move back and forth alternately between the fixed rollers and the movable rollers in a wrapped state, and a prescribed tensile force is applied to the substrates by a force acting on the moveable rollers in the direction away from the fixed rollers. The controller performs control so as to maintain the positions of the movable rollers in the tensioning unit constant.

Example implementations relate to adjusting print medium retrieval. For example, a system may include a printing device that may have a pick roller attached to a pick arm and a servomotor to apply torque to the pick roller. The system may further include a controller associated with the servomotor to determine a measured position of the servomotor relative to an intended position of the servomotor in a particular time frame during the print medium retrieval. The controller may further determine adjustment of the print medium retrieval based on comparison of a pulse width modulation (PWM) magnitude in adjacent time frames.

In a paper feeding apparatus, paper feed rolls in paper feed roll rows for feeding the lowermost one of cardboard sheets placed in a stacked manner on a paper feeding table intermittently one by one toward the printing device are coupled via shafts to separate servomotors. The servomotors are controlled so to be accelerated synchronously and rapidly from a stopped state to a high rotational speed during one cycle of feeding through contact with the lowermost cardboard sheet, while controlled so to be decelerated from the high rotational speed to be stopped rapidly and respectively when determined not to be in contact with the lowermost cardboard sheet.

An automatic cut and transfer coiler and spooler apparatus, system, and method for use generally comprising a rotatable turret with two independently driven spindles thereon wherein the drives for the independent spindles are attached to the turret for selectively rotating the spindles about their own axis independently.

A method for manufacturing a sheet-like member, associated with an absorbent article, using a continuous sheet. The method includes a supplying step, a processing step, and a detecting step. In the supplying step, the continuous sheet is supplied by transferring the continuous sheet to a processing section by transporting the continuous sheet in a direction of transport. The processing step is performed at a predetermined position in the direction of transport, and a portion of the continuous sheet which is to be the absorbent article is processed by the processing section at an interval in the direction of transport. In the detecting step, a trace of the processing left on the continuous sheet is detected. In the supplying step, a direction-of-transport tension value of the continuous sheet at a time of transferring the continuous sheet to the processing section is adjusted based on the detection result.

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.

Disclosed are examples of a system for regulating the longitudinal strain in a longitudinal member being conveyed in a machine direction. The system may include a downstream mechanism that draws the longitudinal member in a machine direction, first and second control points upstream of the downstream mechanism, and a strain control mechanism disposed between the first and second control points. The strain control mechanism may include a strain motor with a drive shaft to which a travel path extension arm is coupled, and a travel path extension guide mounted on the travel path extension arm and in contact with the longitudinal member. The system may be configured and arranged such that rotation of the drive shaft effects rotation of the travel path extension arm and of the guide, thereby altering the distance of a travel path segment of the longitudinal member between the first and second control points.

A film intermittent carrying device: includes a film delivering mechanism, a delivering and accumulating mechanism, accumulating the film and discharging the film, a winding and accumulating mechanism accumulating the film while discharging in an amount corresponding to an amount of the film discharged, and a film winding mechanism taking-up the film constantly. The delivering and accumulating mechanism includes first and second fixed rollers, an upstream-side movable roller moving to pass through a middle position between the first and second fixed rollers, and an upstream-side friction preventive unit configured to reduce a friction between the film and the upstream-side movable roller. The winding and accumulating mechanism includes third and fourth fixed rollers, and a downstream-side movable roller moving to pass through the middle position between the third and fourth fixed rollers, and a downstream-side friction preventive unit configured to reduce a friction between the film and the downstream-side movable roller.
