Abstract:
1. Fastening tool ( 10 ) for applying parts ( 12 ), in particular plastic parts ( 12 ), to objects ( 14 ), wherein the plastic parts ( 12 ) are supplied in the form of a belt ( 20 ) in which the plastic parts ( 12 ) are linked together by means of at least one flexible web ( 22 , 24 ) wherein the fastening tool ( 10 ) is designed to transport the belt ( 20 ) by means of a feed mechanism ( 62 ) such that one plastic part ( 12 ) at a time is delivered to a fastening position ( 18 ), and wherein the feed mechanism ( 62 ) has a fluid drive ( 64 ) that is coupled by a translation-rotation converter ( 68 , 70 , 72 ) to a transport gear ( 84 ) that is rotatably mounted on the fastening tool ( 10 ) and is designed to positively or nonpositively engage the belt ( 20 ) in order to transport it, characterized in that the translation-rotation converter ( 68 , 70 , 72 , 80 ) has an overrunning clutch ( 72 ) with a bidirectionally rotating driving gear ( 74 ) and a driven gear ( 76 ), the driving gear ( 74 ) being kinematically coupled to the fluid drive ( 64 ), the driven gear ( 76 ) being coupled to the transport gear ( 84 ) in a rotationally fixed manner, the clutch ( 72 ) being constructed so that the driven gear ( 76 ) is driven only by unidirectional rotation of the driving gear ( 74 ).
