Abstract
Mould portions supporting arms of a mould arrangement are moved by drive means between mould-open and mould-closed conditions. The drive means comprises two vertical drive shafts (20) connected to the supporting arms and arranged to move the arms when turned in opposite directions by motor means (40). The motor means (40) is connected to the drive shafts (20) by connecting means comprising a driving pulley (70) driven by the motor and two driven pulleys (72 and 74) mounted on the shafts (20). The pulleys are interconnected by belts (76,78,80 and 82) whose ends are attached to the pulleys. During motion in each direction, two of the belts move the driven pulleys and hence turn the shafts (20) while the other two belts act to maintain tension in the first-mentioned belts.
