Abstract: A clothes dryer includes a motor adapted to be mounted on a frame of the dryer for driving a dryer belt to rotate a drum of the dryer. The motor includes a rotor adapted to rotate the belt, at least one winding energizable to cause rotation of the rotor, and a first switch operable to control energization of the winding. A second switch has a sensor for sensing belt breakage. The second switch is mounted on the first switch and is electrically connected to the winding so that when the belt is no longer sensed, the second switch stops operation of the winding and thereby stops rotation of the rotor.

Abstract: A device (21) and method for removing a broken pulp web (27) from a pulp dryer and a maintenance platform (23) comprising such a device. The device (21) comprises an actuator (31), a pulling means (33) functionally coupled to the actuator and adapted to be driven by the actuator, and a gripping means (1, 11) coupled to the pulling means (33) and comprising means (4, 5) for engaging to the pulp web. The actuator is arranged to actuate the gripping means via the pulling means. The actuator is used to pull the gripping means and along with it, the pulp web out from the pulp dryer.

Abstract: A method of cooling a material web includes, after drying a material web, moving the material web in a given direction on a meander-shaped web path over a cooling cylinder and at least one other cylinder disposed at a location selected from a group thereof consisting of a location upline and a location downline from the cooling cylinder, as viewed in the given direction of the web path, providing for the moving of the material web to be with at least partial looping thereof over the cooling cylinder and the other cylinder, and arranging the cylinders with respect to one another so as to exclude contact pressure with one another that is in effect between two respective ones of the cylinders; a device for performing the method.

Abstract: A web positioning device includes one or more ports positioned in or adjacent at least one platen of a gap drying system, wherein upon generation of a vacuum force through each port, movement of a web of material conveyed through the gap drying system is arrested by drawing a first face of the web of material into contact with a portion of the web positioning device immediately surrounding each port. A method for controlling movement of a portion of a web of material using the web positioning device is also presented.

Abstract: An improvement to a coal processing system where hard materials found in the coal may cause jamming of either inflow or outflow rotary airlocks, each driven by a reversible motor. The instantaneous current used by the motor is continually monitored and compared to a predetermined value. If an overcurrent condition occurs, indicating a jamming of the airlock, a controller means starts a "soft" reverse rotation of the motor thereby clearing the jamming. Three patterns of the motor reversal are provided.
