Apparatus for stringing electrical components into a belt for convenience in handling, packing and despatch to customers, the components having two connecting wires extending in opposite directions and the belt comprising two runs of double adhesive tape to trap the connecting wires and incorporate the components into the belt in ladder-like formation. The components are fed down a guide and released one-by-one by a blocking slide to a transfer device comprising two rotating discs having slots for receiving the connecting wires and being associated, if necessary, with stationary projections for preventing them from falling out. The transfer discs may be associated with specially shaped rollers for straightening the connecting wires. The components then enter the actual belt make-up machine of the apparatus, comprising a pair of toothed wheels, each in two parts whose spacing is adjustable and each associated with a guide roller and a pressure roller. These rollers serve for guiding respective pairs of adhesive tapes, coming from respective reels into position to receive the opposite connecting wires of the components and then to trap them and thereby form the belt. The toothed wheels and the transfer discs are connected by a change-speed gear, which may take the form of a draw-key type (stepped conical or wedge type) gearing, making it possible to achieve easily a wide range of adjustment of the spacing of the components in the belt. Certain other adjustment means and features of the apparatus are described. |
