Abstract: An adjustable conveyor for conveying a printed circuit board includes a frame, a first track including a first conveyor belt, a second track including a second conveyor belt, wherein the first track and the second track are mounted on the frame so that the first track and the second track are parallel to each other. Each of the first track and the second track includes a first element and a second element that are slidably connected to each other so that a space between the first element and the second element is adjustable so as to change a length of the respective track. Each of the first elements includes a plurality of slide blocks. The slide blocks are slidably mounted on the first elements in an overlapping manner so that an amount of overlap between the slide blocks is adjustable as the space between the first element and the second element is adjusted. The conveyor also includes a device for simultaneously driving the first and second conveyor belts.

Abstract: Electronic components, such as resistors with bodies of different lengths and axially protruding leads, are fed along a feed path and between a pair of rotating members. Each rotating member has fingers that are flexed away from the feed path for reception of the component bodies between cooperating fingers of the rotating members, after which these fingers close onto the bodies to center them on the feed path.An opposed pair of the flexible fingers, one from each rotating member, retain each component in a centered condition along the feed path until corresponding leads of consecutive components are taped together at a subsequent taping station to form a ladder-like belt of components.
