Rotational moulding machine

A rotational moulding machine according to any one of the preceding claims, further comprising;

• a first arm and a second arm of said at least one arm;
• said respective connecting portions of said first and second arms opposing each other in spaced apart relationship and arranged, in use, on opposing sides of said mould.

A rotational moulding machine according to any one of the preceding claims, further comprising a second motor connected outside of said oven to one of said at least one arms;

• and
• a drive belt connected between said first motor and said connection portion;
• said connection portion thereby being rotatable by said second motor.

A rotational moulding machine according to any one of the preceding claims, wherein said first conduit portion and said second conduit portion are on opposite sides of said cabling receiving section.

A rotational moulding machine according to any one of the preceding claims, further comprising rotatable electrical connectors for connecting cables on said mould to said cabling in one of said at least one arms.

A rotational moulding machine according to any one of the preceding claims, wherein said at least one arm is a elongate, hollow and generally L-shaped.

A rotational moulding machine according to any one of the preceding claims, further comprising a rotatable conduit for, in use, providing fluid from one of said at least one arms to said mould.

A rotational moulding machine according to any one of the preceding claims, wherein said fluid is air.

A rotational moulding machine according to any one of the preceding claims, wherein said cabling receiving section is part of said first conduit portion.

A method of cooling cabling housed in a cabling receiving section of an arm of a rotational moulding machine, said machine having an infra red oven, and said cabling being connected between outside of said oven and a connection portion connecting a mould inside said oven to said arm, said method comprising the steps of:

• providing said arm with a first conduit portion for the flow therein of cooling fluid from outside of an oven towards an end of said arm connected to a mould in said oven;
• providing said arm with a second conduit portion for the return flow therealong of said cooling fluid from inside of said oven to outside of said oven;
• providing a flow of cooling fluid from outside of said oven to inside said oven through said first conduit portion and out of said oven through said second conduit portion to cool said cabling thereby to protect said cabling from high temperatures in said oven.
