A printing apparatus is configured to perform in a first mode in which a second driving unit drives a second spool to feed out a sheet from a roll to a printing unit via a second guide, the printing unit performs printing on the fed sheet, and a basket unit receives the printed sheet printed on by the printing unit, and a second mode in which a first driving unit drives a first spool to feed the out the sheet from a roll to the printing unit via a first guide, the printing unit performs printing on the fed sheet, and the second driving unit drives the second spool to wind up the printed sheet printed by the printing unit as a roll.

Lacing engine systems, apparatus, and methods of operation are discussed. In an example, a lacing engine apparatus can include a housing, a drivetrain, and a lace take-up mechanism for retracting a length of lace cable upon activation. The drivetrain can include various reduction gears to reduce rotational speed out of the motor and power the lace take-up mechanism. The lace take-up mechanism can include structures such as a double-yoke, a radial pulley including an outer rotating disc and an inner stationary disc, a variable take-up spool, or a zip-strip mechanism.

The present disclosure relates to systems and methods related to the suppression of invasive plant species by laying down a fabric over beds of such invasive plants. A watercraft with a fabric laying mechanism is provided with the mechanism automatically guiding the fabric from a fabric stockpile to a frame that spreads the fabric prior to the fabric being laid over the underwater plant bed. The watercraft may be provided with a device for dispensing material over the fabric that has been laid down to weigh down or hold down the fabric. Preferably, the fabric is biodegradable and the material is natural to the area. In one implementation, the fabric (e.g jute burlap) is coarsely woven from natural plant fibers.

Cable tensioning based on load profiles is provided. A system can include a dispenser of a charger and one or more processors. The system can detect a characteristic of a vehicle. The system can determine, based at least in part on the characteristic of the vehicle, an amount of force to apply to a cable. The system can provide an instruction to cause the dispenser to apply the amount of force to the cable.

The specification discusses various lacing engine configurations for use in an automated footwear platform. For example, lacing engines with mechanisms to detect lace cable position and/or lace cable tensions are discussed. In an example, the lacing engine can include a housing, a lace spool and a detection mechanism. The lace spool can be at least partially disposed within the housing, and be adapted to collect a portion of the lace cable in response to rotation in a first direction during tightening of the footwear platform. The detection mechanism can detect a state of the lace cable manipulated by the lacing engine.

In an example, a lacing engine apparatus can include a housing and a drivetrain. The housing can be securable within a footwear article. The drivetrain can include a motor, a sun gear, a planet gear, a rotating ring gear, and a spool. The spool can be secured to the ring gear and can be rotatable therewith. The spool can be configured to control a lace of the footwear article and can be configured to wind the lace as the ring gear rotates in a first direction.

Method and apparatus for producing and drawing-off a web-shaped product (2) with a production machine (1) and two clamp carriers (7.1, 7.2) with clamps (10.1, 10.2). The clamp carriers (7.1, 7.2) are driven moving back and forth parallel to a drawing-off direction of the web-shaped product (2). The clamp carriers (7.1, 7.2) are respectively drivable with a pair of drive spindles (14.1, 14.2), which are arranged in such a manner so that the web center of the web-shaped product (2) within the apparatus (6) extends in an area between the two drive spindles (14.1, 14.2) of the respective clamp carrier (7.1, 7.2). The method is characterized in that the web-shaped product (2) is produced with successive main sections (4.1, 4.2, 4.3, 4.4) and auxiliary sections (3.1, 3.2, 3.3, 3.4, 3.5), and that the clamps (10) are actuated in such a manner so that the opening and closing of the clamps (10) takes place only in the time segments of the production in which an auxiliary section (3.1, 3.2, 3.3, 3.4, 3.5) of the web-shaped product (2) is being produced.

This invention relates to a method of controlling the operation of a winder in which method while forming at least one fiber web roll the fiber web is brought on the web roll via a nip formed by a first support drum and the web roll, which first support drum is driven by a first drive assembly (20) applying controllable torque to the drum and the winding force is applied to the web roll by a second drive assembly (22). In the method the second drive assembly (22) is controlled based on the indicative speed difference of the second drive assembly (22) and setting a friction coefficient for determination of maximum winding force.
