The new workpiece is clamped while in loading position. The rotary device is mounted on a shaft 32, twelve pairs of clamps 60, 112 engaging the attaching face and tread face, respectively, being carried on the shaft. The tread plates are carried on a separate spider, angularly adjustable so that heels of differing heights may be operated on. The attaching-face plates are carried by levers 54 pivoted at 48 and each urged towards the tread plate by a spring 62. Each lever also has an arm 68 carrying a roll 70 co-operating with a cam 94 to open the clamp at the operator's position. The cam is capable of slight angular motion, a treadle 80 swinging the same against the pull of a spring 84. A fixed bracket 100 carries a pivoted arm 104 urged anti-clockwise by a spring 110 and supporting a cam 96 which acts as a buffer to the roll 70 as it leaves the cam 94. To each tread-plate is pivoted a pair of arms 128 joined by bars 130, 139, urged anticlockwise by a spring and carrying a roll 138. The roll co-operates with a cam member 140 pivoted at 146 and resiliently positioned by a spring 154 and a spring plunger 150. After leaving the cam 140, the cam travels on flats 160. The lifts are assembled between an adjustable breast gauge 182 and jaws 190, 226. Each of the jaws is pivoted on an arm such as 194 maintained horizontal by a spring plunger 210, the forward jaws being adjustable at their lower ends by a right and left hand screw 220 actuating levers 214. The corresponding abutment for the rear jaws is an adjustable slide 234. In operation, a pile of pasted lifts is assembled between the jaws and a starting handle actuated to cause a presser foot to compress the assembly and a driver to drive a nail to hold the lifts together. Simultaneously the shaft 32 is rotated 30 degrees. The assembly is placed between the plates of the open clamp, the bar 130 acting as a gauge and the treadle depressed swinging the cam 94 and allowing the clamp to close. As a clamp approaches the loading position the roll 138 carried by the open clamp rides on the lower surface 157 of the cam 140, yields against a spring and ejects the heel as the clamp opens, the roll passing to a cam 160 after leaving the cam 140.
