This is one of the more modern forging devices. Their development in the 1920s (?) allowed great time and labour savings to be made in the production of tools and impliments that had, for example, a tapering handle or shank.
Obtained from Greenhill Forge, Sheffield.
A Roll Forge consists of a two rollers mounted parallel to each other in a stand, just as in a rolling mill. However each roll has a flat section with mounting and secuting slots into with 'chills' are secured. The rolls rotate together but in opposite directions, so the 'chills' always come together from the back to the from. As the rolls have non adjistable gap between them, all alterations to the process must be done by changing the 'chills'.
To produce a forging, the work peice is pushed between the rollers. As the chills come round, they firstly grip the work and then squeeze it, pushing it back out towards the operator in the process.
