13 that exercises sufficient forces for the formation of the indentations 2 on the end of the wire 1 the cylinder 13 of the press is activated by a hydraulic valve that need not be depicted thus versions of exemplary systems for placement of covers 3 on the ends of wires 1 situate a formation press 10 along the length of a production line for the ends of transverse wires 1 so that there result indentations and protrusions 2 subsequently feeding unit 20 for covers 3 places covers 3 on ends of the transverse wires 1 of a spacer mesh 1 a it should be understood that the system may be controlled by an electronic computer and all of its working phases may be generated automatically one or more ends 1 may be formed simultaneously from an equal number of presses 10 and the same number of covers 3 are placed on the ends of the wire 1 by an equal number of cover 3 feeding mechanisms 20 the placement of the covers 3 occurs at the placement station 19 the covers 3 are guided in the perpendicular direction in series as depicted in fig3 a inside the guide 23 of cover feeding mechanism 20 in the mechanism 20 base there is a rotor 22 with a receiver 22 a of dimensions corresponding to the dimensions of the cover 3 and having two positions considering fig3 a and 3c one position is towards the top for receiving a cover 3 from the feed guide 23 and one horizontal for feeding 23 a the.
