摘要:
The invention relates to an output device for outputting planar segments of a web-shaped sheet product from a roll, wherein the output device comprises a drum and a cutting device. The cutting device has a blade carrier arranged in the drum, which blade carrier comprises at least two cams, and at least one cam track. The drum comprises at least two cam guides, which are arranged on an end face of the drum. In a jacket, the drum comprises an opening for the exiting of at least part of at least one blade. At least one first cam engages in the cam track in order to move the blade carrier, during a rotational motion of the drum about a longitudinal axis of the drum, in such a way that the blade arranged on the blade carrier passes through the opening in the jacket. A second cam engages in at least one cam guide of the drum in such a way that, during a motion of the blade carrier, the blade carrier tilts about a longitudinal axis.

Dispenser suitable for dispensing absorbent sheet material from a roll disposable within said dispenser. The dispenser including: a dispenser body; a rotational shaft suitable for penetration of said roll; a drive unit; and an energy storage system for storing energy. The drive unit is rotationally coupled to said rotational shaft, which includes engagement means suitable for rotationally locking said rotational shaft with said roll. Externally caused rotation of said rotational shaft drives said drive unit, thereby enabling accumulation of energy in said energy storage system, and said drive unit is configured to be powered by energy from said energy storage system for temporarily rotating said rotational shaft. The engagement means includes at least one projection and/or at least one recess arranged on a circumferential outer surface of said rotational shaft for radial engagement with said roll.

Apparatus for dispensing paper from rolls which feeds continuously, roll to roll, and does not require extra procedure to bring stub roll into position. The apparatus has means for holding and positioning at least first and second rolls of paper with respect to each other; means for dispensing paper from the first roll; means for dispensing paper from the first and second rolls simultaneously whent he first roll reduces to a predetermined diameter of paper, means for positioning the depleted first roll for replacement without the necessity of removing the second roll; and, means for dispensing from the second and replacement rolls simultaneously when the second roll reduces to a predetermined diameter of paper. The apparatus also has a capacity-change-based proximity sensor comprising a circuit according to a balanced bridge principle where detection is based on detecting a phase difference, which depends upon the amount of detected capacitance difference or change. The proximity detector senses when a hand is placed near the dispenser, and thereupon dispenses a set amount of towel. It does not keep dispensing the towel. The hand must be withdrawn and placed in proximity to the sensor again. The proximity sensor incorporates "static" and noise-immunity circuitry. The dispenser incorporates means for dissipating static charges to a local ground.

In one aspect, the invention provides a replaceable winding roller for flat strip material in a towel dispenser. The roller comprises a cylindrical roll, an outer surface forming a winding surface for the flat strip material, the roll comprising a groove axially extending from one end part of the roll to another end part of the roll. The groove is open on the one end part. The roller further comprises a freestanding pin being connected to the another end part of the roll, forming a gap between the groove and the pin into which the strip material may be slid. The freestanding pin is positioned in the groove below the winding surface. The gap distance is at least the width of the material in an uncompressed state. It is an object of the invention to provide a winding roller that may be easily removed from the roll of used cloth.

The device of the invention is characterised in that it comprises an envelope fixed (10) about a drum (3) and partially surrounding said drum while leaving at the front portion a free access for the passage and introduction and outlet of a wiping material before and after a cutting operation, the function of said envelope being to protect the drum and its related cutting device and to ensure the passage of the strip of material during a cutting phase, wherein the outer portion of the envelope defines a bearing plane for a strip of material from a service roll in a finishing phase, said envelope including oblong openings (10d) formed along the envelope, the device being also characterised in that it comprises, behind the drum and the envelope (10), a device for receiving the service material strip in a finishing phase including two components (17-18), i.e. a stationary component (17) for receiving the spool of material in a finishing phase, and a component (18) that is mobile relative to the stationary component in order to allow or prevent, depending on the position thereof, the access to the stationary component (17), the mobile component being provided with a means (18c) in the form of teeth present in a number and in positions that correspond to the number of openings (10c) formed in the envelope, said teeth, depending on the position of the mobile component, bearing against the strip of material from the spool in the finishing phase which is itself bearing against the envelope (10), the device being further characterised in that, depending on the presence or absence of a material strip from the material spool in a finishing phase, the component (18) penetrates or does not penetrate into said envelope.

Dispenser apparatus (1, 3) for dispensing flexible sheet material (1001) including material- recognition apparatus permitting the dispenser to recognize sheet material from an authorized source and to be enabled for operation with such material. The material-recognition apparatus may include a sensor (138) mounted in the dispenser in position to scan a code (10 19), preferably located on the core (1005) on which the sheet material is wound. The sensor generates a code signal corresponding to the code. A control circuit (49) receives and validates the code signal. Sheet material dispensing is allowed if the code is valid or is not allowed if the code is invalid.
