Rewinder for the production of paper logs adapted to guide and transversely pre-cut a paper web along a predetermined path, adapted to wind a predetermined amount of the paper web on a core in a winding station, and including a threading mechanism for threading the web along said path. The threading mechanism includes a dragging unit provided to engage the web to drag it along the path with a predetermined feed direction and at least one dragging member to engage a respective flap of the web preceding the production of the logs. The dragging unit is located downstream of the winding station and is adapted to release the flap of the web from the dragging member, the release means being arranged downstream of the dragging so as to intercept the flap of the web and disengage it from the dragging while the web is fed.

In a method for removing a wrapping, such as plastic film, from a roll of material an apparatus is used, which has a roll supporting unit, and a cutting means. The roll supporting unit is configured to rotate the roll supported thereon, and the cutting means is movable into cutting abutment against the envelope surface of the supported roll for removal of the wrapping during rotation of the roll.

A recording medium processing apparatus includes: a first conveyance unit that conveys a recording medium; a cutting member that is provided alongside the first conveyance unit in a width direction of the conveyed recording medium and cuts the recording medium along a conveying direction of the recording medium; a second conveyance unit that is located upstream of the first conveyance unit in the conveying direction and conveys the recording medium having reached a predetermined conveyance route; and a preventing or avoiding unit that, in the recording medium which is conveyed by the first conveyance unit and whose upstream end in the conveying direction has not passed the predetermined conveyance route, prevents or avoids a portion overlapped with the cutting member in the conveying direction from being pulled by the second conveyance unit.

A recording medium processing apparatus includes a pair of first conveyance units provided at an interval in a width direction of a recording medium to be conveyed, each of the first conveyance units pinching and conveying the recording medium; a cutting member that cuts the recording medium being conveyed by the first conveyance units along a conveyance direction of the recording medium; and a second conveyance unit provided between the pair of first conveyance units in the width direction and inside the cutting member, the second conveyance unit pinching the recording medium and conveying the recording medium, together with the pair of first conveyance units, at a conveyance speed of the recording medium lower than each of the pair of first conveyance units.

An image forming apparatus having a first container, a second container, an image forming device, a medium conveyer, a command acquiring device, and a controller, is provided. When a length of the medium to be conveyed is equal to or smaller than a first predetermined length, the controller controls the medium conveyer to convey the medium from the first container and the image forming device to perform an image forming operation on one of a first side and a second side of the medium, and, after the medium is accommodated in the second container in an orientation with the other of the first side and the second side to be used as the image-formable side, control the medium conveyer to convey the medium from the second container and control the image forming device to perform the image forming operation to the medium conveyed from the second container.
