A tandem rolling mill is a rolling mill used to produce wire and sheet metal. It is composed of two or more close-coupled [clarification needed] stands, and uses tension between the stands as well as compressive force from work rolls [clarification needed] to reduce the thickness of steel. It was first patented by Richard Ford in 1766 in England.
The coil groups are frequently manufactured with flyer winding machines and put onto the insertion tool with a transfer instrument. In small-batch manufacturing, the coil groups are relocated manually from the winding masks to the insertion tool using transfer instruments.
The arc spring (also known as - bow spring, curved spring, circular spring or "banana" spring) is a special form of coil spring which was originally developed for use in the dual-mass flywheel of internal combustion engine drive trains. The term "arc spring" is used to describe pre-curved or arc-shaped helical compression springs.
A helical torsion spring actually works by torsion when it is bent (not twisted). [2] [3] We will use the word "torsion" in the following for a torsion spring according to the definition given above, whether the material it is made of actually works by torsion or by bending.

Spring steel is a name given to a wide range of steels [1] used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese , medium-carbon steel or high-carbon steel with a very high yield strength .
Roll forming, also spelled roll-forming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired cross-section. The strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired ...
The force in the spring is (roughly) the vertical force at the contact patch divided by the motion ratio, and the spring rate is the wheel rate divided by the motion ratio squared.
