摘要： The present invention provides an improved belted reel which is particularly well suited for the winding of soft, bulky tissue webs and overcomes the limitations of the prior art. The belted reel is capable of providing coordinated web tension and nip control by providing the winding parent roll with two nip points—the first nip formed between the winding roll and the second between the winding roll and a second support drum. Preferably the drum encircled by the endless belt lies above the second support drum and the first and second nip points lie in the same vertical plane.

摘要： A medium supplying apparatus includes a control unit. The control unit executes: a first control in which, in a case where a double feed detecting sensor detects a double feed of media, rotation drive of a separator roller is stopped, and a retard roller is caused to convey the media to an upstream side in a conveying direction; and a second control in which, after the execution of the first control, the rotation drive of the separator roller is restarted, and, in a case where the double feed detecting sensor detects a double feed of the media, a conveying load applied is set to be higher than that at the time of detecting the double feed before the execution of the first control, the rotation drive of the separator roller is stopped, and the retard roller is caused to convey the media to the upstream side in the conveying direction.
