An apparatus for automatically attaching a malleable cylindrical sleeve or hub to a cylindrical member, such as the neck on a syringe barrel. The syringe barrel is rotatably supported in an upright position axially aligned with and above a hub support which is rotatably mounted upon the frame of the apparatus in axial alignment with the syringe neck. The hub is simultaneously rotated and moved upwardly into engagement with the neck of the syringe barrel, which thereafter rotates with the hub. Deforming rolls engage the upper edge of the hub and rotate with it as they spin the hub onto the hub receiving neck of the syringe barrel. The assembled barrel and hub are then carried away from the apparatus.
