Abstract
A round wire is cold formed in a first pair of forming rolls to produce a flat metal ribbon cable having a specified width, followed by cold forming the flat metal ribbon cable in a second pair of forming rolls to produce a flat metal ribbon cable having a specified thickness and said specified width without any additional edge processing.
Claims22
A process for the production of metal ribbon cable comprising:
- cold forming a round wire in a first pair of forming rolls to produce a flat metal ribbon cable having a specified width;
- wherein said first pair of rolls are separated by a gap which determines the width of said ribbon cable;
- cold forming said flat metal ribbon cable in a second pair of forming rolls to produce a flat metal ribbon cable having a specified thickness and substantially said specified width without any additional edge processing;
- measuring the width of said ribbon cable following forming in said second pair of rolls;
- and
- adjusting the gap of the first pair in accordance with the measured width in order to obtain a desired width.
3 more elements
An apparatus for the production of flat metal ribbon cable by cold rolling, said apparatus comprising:
- a first pair of forming rolls for cold forming a round wire to produce a flat metal ribbon cable having a specified width;
- a second pair of forming rolls for forming said flat metal ribbon cable to produce a flat metal ribbon cable having a specified thickness and substantially said specified width, said second pair of forming rolls having axes of rotation which are parallel to the axes of rotation of the first pair of forming rolls;
- and
- a drawing device for reducing the diameter of said round wire upstream of and in-line with said first pair of forming rolls.
1 more element
A process for the production of metal ribbon cable comprising:
- cold forming a round wire in a first pair of forming rolls to produce a flat metal ribbon cable having a specified width, wherein the ratio of the diameter of the round wire to the thickness of the flat ribbon cable after forming in the first pair of rolls is between 5 and 10;
- and
- cold forming said flat metal ribbon cable in a second pair of forming rolls to produce a flat metal ribbon cable having a specified thickness and substantially said specified width without any additional edge processing.
