Wembley Sportsmater was the rotational moulding side of Mettoy. We had 7 moulding machines, 4 x 8 arm, 1 x 5 arm and 2 x 3 arm machines making footballs, playballs, spacehoppers and other vinyl toys such as Dolly Drops, as well as powder bases for punchballs, toy boxes in the form of castles and dolls houses - and much more.
Harlestone Road was a myriad of departments. Tom Chapman ran Kites - my dad and I flew pre-production stunt kites in Cornwall. No-one had seen such kites and they were a sensation. There was a carpenter's shop where they made stands for Toy Fairs etc. Production lines were set up for whatever was the latest craze (make money while you can seemed to be the ethos). My dad says that in 1966 they made 25 million footballs. They ran three shifts through 24 hours with 4 x 8 arm machines on balls. When I was Planning Manager we were making 8 down to 6 million balls per year, 2 x 8 arm machines mostly on one shift, sometimes two shifts when demand was up.
