A conveying apparatus includes: a conveyor configured to convey a web while unwinding the web from a web roll; a brake configured to apply brakes to rotation of the web roll; and a controller configured to perform control to unwind the web from the web roll and convey the web with the conveyor while giving tension to the web by applying brakes to the rotation of the web roll using torque of the brake. The controller is configured to determine the torque of the brake during deceleration of the web to be a value depending on an inertial load of the web roll.

Printer spindle assembly is provided including media spindle having first end and second end, a commutator disposed circumferentially at first end, at least two brushes in electrical contact with commutator and connected to voltage source, a plurality of electrically conductive springs serially disposed on media spindle in electrical communication with commutator, and a continuous electrically conductive path formed of electrically resistive material disposed along longitudinal axis of media spindle and configured to be in electrical contact with first spring end of one or more electrically conductive springs in the compressed state to form series circuit. Voltage source, brushes, and commutator form closed electrical circuit. Each electrically conductive spring is configured to be in uncompressed state in absence of media on media spindle and one or more of electrically conductive springs is configured to be in compressed state in presence of media on media spindle.

A method, apparatus and program product may utilize packaging material quality compensation to sense changes in certain characteristics of a packaging material that can be associated with increased risks of film breaks, and automatically make certain changes in machine settings to mitigate the impact of those enhanced risks.

A print apparatus has a supporting section for supporting a roll of a continuous sheet, a driving mechanism having a motor for rotating the roll supported by the supporting section, a detection unit configured to detect a rotation state of the roll supported by the supporting section, a conveyance roller for conveying the continuous sheet drawn out from the roll and a print unit configured to form an image on the continuous sheet conveyed by the conveyance roller. A control unit is configured to obtain information indicating a moment of inertia of the roll supported by the supporting section based on detected values of the detection unit and to adjust a driving torque of the motor based on the obtained information, intermittently during printing.

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.

A sheet interleaver is provided for a slicing machine that includes a slicing plane for slicing an elongated food product and a sheet of web material beneath the elongated product. The interleaver includes a supply of web material, a drawing station, and a feed station. A tensioning station is disposed between the supply of web material and the drawing station to maintain the tension of the web material at a pre-determined tension. A web accumulation station is between the drawing station and the feed station to provide a slackened length of web material within an acceptable range of slack between the drawing station and the feed station. The supply of web material is disposed on a spool which rotates about a cylindrical shaft. The cylindrical shaft has a braking mechanism which protrudes from the shaft to generate a frictional force against the spool.
