Abstract
In a suction roller for the movement of sheet-shaped workpieces, particularly for their acceleration or braking, economical production and a design advantageous for flow technology are achieved by providing a wheel body having channels starting at one face, which are open on at least one side and which rotate in sequence past a fixed suction nozzle positioned on one face, as well as a surrounding band (toothed belt) applied to the external circumference of the wheel body with protrusions (teeth) extending outward and indentations between them, with each indentation connected by means of at least one connection boring with a channel.
Claims13
A suction roller for the movement of sheet-shaped workpieces, particularly for their acceleration or braking, whereby a wheel body having channels starting at one face, which are open on at least one side and which rotate in sequence past a fixed suction nozzle fitting closely against one face, as well as a surrounding band applied to the external circumference of the wheel body with protrusions extending outward and indentations between them, with each indentation connected by means of at least one connection boring with a channel, said protrusions having an approximately rectangular cross section with an external surface having a good grip.
A suction roller for the movement of sheet-shaped workpieces, particularly for their acceleration or braking, whereby a wheel body having channels starting at one face, which are open on at least one side and which rotate in sequence past a fixed suction nozzle fitting closely against one face, as well as a surrounding band applied to the external circumference of the wheel body with protrusions extending outward and indentations between them, with each indentation connected by means of at least one connection boring with a channel, said wheel body consisting of a hub part with an integral covering disk of larger diameter on one face and a covering disk which can be put onto the other face of said hub part.
