Patent ID: 8091760

Claim:
Device for fixing conductor tracks ( 22 , 24 ) on at least one first main-surface ( 20 o ) of at least one solar cell ( 20 ), including the following features: 1.1 a transport installation on which a series of solar cells ( 20 ) are arranged at a distance to each other and moveable in a transport direction (T), 1.2 a series of conductor tracks ( 22 , 24 ) extend along the first main-surface ( 20 o ) opposing the transport installation of each solar cell ( 20 ), 1.3 at least one crossbar ( 30 ) moveable from a starting position with a distance to the first main-surface ( 20 o ) to an operating position in which a series of hold-down devices ( 50 ) that are protruding from the crossbar ( 30 ) towards the first main-surface ( 20 o ) of the solar cell ( 20 ) press along a plane onto the corresponding conductor tracks ( 22 , 24 ) wherein 1.4 the hold-down devices ( 50 ) are springs ( 52 ), one end of each being mounted to the crossbar ( 30 ) and each being provided at its other, free end, with at least one spherical body ( 54 ) that is resting on the corresponding conductor track ( 22 , 24 ) in the operating position of the crossbar ( 30 ) wherein 1.5 said hold-down devices ( 50 ), in their unloaded condition, extend at an angle not equal to 90 degrees to the corresponding surface ( 20 o ) of the solar cell ( 20 ).
