  • Patent number: 5876764
    Abstract: A machine includes a stick hopper for dispensing sticks one by one and a device for transferring each stick to a chuck between whose jaws the stick is held while protruding into a basin containing a sugar sprayhead. The chuck is driven rotationally, as is the sprayhead, during a cotton candy forming operation. The hopper containing sticks includes a cylinder with a horizontal or substantially horizontal axis. The cylinder is mounted to pivot about its axis and is associated with a motor. The cylinder is further equipped on its internal face with at least one lengthwise bar delimiting a cavity that matches the shapes of the sticks, the cavity being provided in the face of the bar that faces forward in the direction of rotation of the cylinder. The cylinder contains, below its uppermost generatrix, a device for collecting each stick picked up by the bar in the hopper and releasing the latter under the effect of gravity.
