Provided is a sheet processing apparatus, including: a regulation portion configured to contact with an end edge of a sheet to be conveyed and to regulate a position of the sheet; a position adjustment portion configured to perform position adjustment on a sheet in a direction along an end edge of the sheet of which the end edge is in contact with the regulation portion; a folding portion configured to perform folding processing on a sheet which has been regulated by the regulation portion; and a control portion configured to execute: a first mode of causing the folding portion to perform the folding processing on a sheet which has been regulated by the regulation portion, without causing the position adjustment portion to perform the position adjustment on the sheet; and a second mode of causing the position adjustment portion to perform the position adjustment with respect to the regulated sheet.

The invention relates to a brake device (1) for braking an elongate medium (10) that is to be wound up, having an energy recovery device (16a; 16b; 16c; 16d) which is coupled to the at least one braking roller (14a) and which is designed to act on the at least one braking roller (14a) with a predefined braking moment in order to brake the elongate medium (10) that is to be wound up. The invention furthermore relates to a method for operating a brake device (1) for braking an elongate medium (10) that is to be wound up.

A packaging machine packages items using film. The packaging machine includes: a film transporter for feeding film; and a cutting device for cutting film. The cutting device is transferrable by a driving force from a rest position into an extended position. The film is severable by the cutting device in the extended position. The cutting device is connected to a housing surrounding the cutting device via a return mechanism. The return mechanism is activatable upon the cutting device being transferred from the rest position into the extended position. A return force in a direction of the rest position is exertable by the return mechanism in the activated state on the cutting device in its extended position, the force being greater than a return resistance of the cutting device in its extended state by which the cutting device is held in the extended state without action of the driving force.

A media processing device with a housing includes: a motorized media unit transporter to drive a media unit along a media processing path between an unprocessed media unit source and a processed media unit output; an auxiliary media unit transporter including a roller connected to a converter, and a bias member connected between the converter and the housing. In a first operating mode, the auxiliary transporter receives the media unit from the transporter to drive the roller and the converter; rotation of the converter deforms the bias member from a resting position to a primed position. In a second operating mode initiated upon rotation of the converter to a bias release position, the auxiliary transporter propels the media unit by releasing the bias member from the primed position to drive rotation of the converter and the roller as the bias member returns to the resting position.

Provided is an apparatus with automatic belt tensioning. A winding seat includes a first gear and a winding portion fixed at the first gear. A belt is windable around the winding portion, and the first elastic element is connected with the winding portion thus to wind the belt around the winding portion. A rotation preventing element includes a protrusion. When the protrusion retains the first gear, the winding portion is locked to prevent the belt being wound. When the belt is pulled, it drives the protrusion to be separated from the first gear and drives the winding portion to rotate. When the belt is released and the winding speed of the belt is decreased to a certain degree, the protrusion retains the first gear to prevent the belt being wound.
