A shaping-machine for corrugating, knurling or beading circular metal canisters for boot or shoe polish comprises a former and one or more rotatably-mounted rollers adapted to receive over one end thereof the article to be shaped, the former and the roller or rollers having complementary mating surfaces, the roller or rollers being mounted so as to be relatively movable along the former in a path which first gradually brings the roller or rollers into mating relationship with the former and thereafter separates them, and drive-means for effecting such relative movement between the roller or rollers and the former. The machine has a framework 12 supporting an electric motor 13 and a reduction gear 14. Spaced angle-bars 16 and 17 on the framework carry the former 19, a rotatable support-member 20 for the adjustablymounted rollers 21, feed guide rails 22 and delivery guide-rails 23. Drive is transmitted to the support-member 20 by sprocket-gearing 115 and 116. The former 19 consists of two arcuate members 24 and 25 between which is clamped an arcuate strip 27 which projects at an increasing amount from the former and cooperates with an annular recess 69 in the rollers. Intermediate each pair of rollers 21 is a cylindrical stop-member 70. Control means for limiting feed of the articles to the machine from the guide-rails 22 comprises a pivotable spring- loaded catch-member 86. A pressure-plate 90 is urged towards the rollers by springs 105. In operation, tin canisters are fed down the guide rails 22 under gravity. The lowermost can abuts catch 86 and as its rim is engaged by the leading edge of a passing roller it is withdrawn from the rails and guided on to the roller by the pressure-plate 90. As the can is moved round by the roller it is forced against the side of the roller by the projecting strip 27 in the former causing the can and roller to rotate and form an annular ring in the periphery of the can. When the can reaches the top of the former 19 a pin 112 pierces a hole in the ring and on further movement of the roller the can is lifted off the roller by inclined parts 85 of the delivery guide rails 23 until the can is free to roll under gravity down the guide rails and out of the machine.
