The present application relates to rolled good feeding device and method. Material feeding devices and methods are provided for conveying material from material rolls. The material roll may be adjusted in the longitudinal direction during the feeding process by a rectifying frame to aid in maintaining alignment during the unrolling. Tension of the unrolled material may be monitored and unrolling speeds of the feeding device can be adjusted to maintain tension of the material within a range for that material. Aspects also contemplate elements to feed multiple rolled materials simultaneously for subsequent processing in combination as layered materials.

An example apparatus is disclosed for transporting a substrate through a printing device. The apparatus comprises a shaft to carry the substrate, a motor to rotatably drive the shaft, a motor driver to provide a control signal to the motor to drive the shaft, a transport arrangement to draw the substrate from the shaft, and a controller to cause the motor driver to drive the shaft at a predetermined rotational speed, to cause the transport arrangement to apply tension to the substrate, and to detect a winding direction of the substrate on the shaft based on the control signal.

It is disclosed a substrate selection method wherein the printer comprises a feeding mechanism including a feeding roller to receive a substrate roll and a media advance roller to receive a substrate from the substrate roll, the method comprising: actuating the feeding roller or the media advance roller; measuring a feeding mechanism parameter on the feeding roller or the media advance roller; calculating a substrate parameter in view of the feeding mechanism parameter; determining from a table a substrate type of in view of the substrate parameter; and selecting a preset on the printer in view of the substrate type.

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.

It is disclosed a substrate compactness detection method for a printer wherein the printer comprises a roller to receive a substrate roll and a media advance mechanism to receive a substrate from the substrate roll, the method comprising: determining a substrate thickness; advancing the substrate for a length; measuring an angular displacement of the roller caused by the advancing of the substrate; determining the substrate roll radius by using the length and the angular displacement; and calculating a compactness parameter in view of the substrate roll radius and the substrate thickness.

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.
