Abstract: According to the present invention there is provided apparatus for supplying components for insertion into a printed circuit board, which apparatus comprises a component dispenser, the component dispenser having first and second substantially parallel elongate support elements for supporting components at locations spaced-apart along the lengths thereof and structure for allowing relative movement of the first and second support elements both transversely of and parallel to the length of the first support element so that, in use of the apparatus, relative movement of the first and second support elements of the dispenser causes components supported by one of the support elements to be transferred to the other support element and then returned to the one support element at positions which are advanced along the one support element from the previous positions thereof whereby the components may be supplied one by one from the dispenser.
