ARTICLE FEEDING APPARATUS ABSTRACT OF THE DISCLOSURE An apparatus for intermittently feeding a series of like articles along a path so as to present them in succession to a plurality of operation stations where operations are performed upon the articles in sequence. The apparatus is provided with at least a pair of spaced drums mounted on parallel axes and a one-piece sub- stantially non-stretchable belt passing around the drums. One of the spaced drums constitutes a driving drum and the other of the spaced drums constitutes a low inertia idler drum. The driving drum is provided with a hub having a peripheral flange at one end thereof. A cylindrical rim, providing axially aligned sprocket teeth about its periphery, is mounted about the hub with a first end in abutment with the peripheral flange of the hub. The other end of the rib has at least one notch therein and a spider, mounted on the hub, has at least one arm engagable in the notch of the rim to lock the rim with respect to the hub. Means are provided to rotatably adjust the spider with respect to the hub so as to rotatably adjust the rim, and thus the sprocket teeth, with respect to the hub. The low inertia idler drum is provided with a pair of spaced side plates fixed to a non-rotatable shaft. Opposed coaxial pairs of first roller bearing means are mounted on the side plates such that the axes thereof are substantially parallel to the axis of the non-rotatable shaft. A sleeve is rotatably mounted around the first roller bearing means and opposed pairs of second roller 21 bearing means having axes substanially perpendicular to the axis of the shaft bear against the peripheral edges of the sleeve to provide axial guiding for the sleeve. The non-stretchable belt is of flexible material having non-stretchable elements embedded therein and running longitudinally of the belt so as to give the belt non-stretch characteristics. Inwardly projecting driving teeth are provided along both edges of the belt. The belt has seating elements of a shape to fit the articles regularly and accurately spaced along its length.
