one complete turn they become offset by slightly more than the width of the traction chain 10 so that a plurality of turns 14 can be wound next to each other about the drum 12 when the traction chain 10 is unwound from the drum 12 the links 16 are guided along a second guiding edge 42 and offset in such a manner that when they leave the restraint 26 they are again aligned in a manner analogous to winding it has thereby been found advantageous to manufacture the restraint 26 more specifically the guiding edges 40 42 from pe in order to keep the frictional resistance low fig5 illustrates an alternative restraint 44 that also comprises a first and a second guiding edge 46 48 and that is also disposed at such an incline that the discrete links 16 of the traction chain 10 become offset by exactly one width of the traction chain 10 as they are passed once through the restraint 44 since a number of links 16 are wound into one turn 14 about the drum 12 an offset of between 1 mm and 5 mm preferably of 3 mm is sufficient when the adjacent links 16 u2032 16 u2033 have a width of about 30 mm the restraint 44 is thereby designed in such a manner that the distance between the first guiding edge 46 and the second guiding edge 48 is chosen to allow a driver member 50 mounted to the link 16 to be positively guided it has been found advantageous to manufacture both the driver member 50 and the restraint 26 44 from pe in order to achieve as little friction as possible there it is understood that the exact dimensions of the discrete component.
