PCT No. PCT/GB87/00175 Sec. 371 Date Oct. 29, 1987 Sec. 102(e) Date Oct. 29, 1987 PCT Filed Mar. 13, 1987 PCT Pub. No. WO87/05476 PCT Pub. Date Sep. 24, 1987.In a hydraulically operated pulling over and toe lasting machine both the operative position of the heel support (26), i.e. in which it holds the shoe by engagement with its heel end, and the position from which it initially moves to engage the shoe (the "next start" position) are controlled by electronic circuitry. Thus, an inductance switch (118) is actuated when the heel pad (100) engages the heel end of the shoe, said switch causing the supply of fluid to be shut off and locking the heel support in its operative position. For setting the "next start" position, on the other hand, selector switches (122,124) are provided each of which has an associated timer (T1,T2). At the end of a lasting cycle the heel support (26) is first fully retracted and then moves to its "next start" position under the control of the timer associated with the selected switch.
