摘要： A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

摘要： 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.

摘要： 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.

摘要： An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension sensor and the edge sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.
