Device for winding and unwinding the lower part of fishing line (cast) is a part of equipment for fishing with hook, by which it is solved the problem of visibility in water of lower reinforced parts of lines made of materials visible in water. These parts represent one of the most loaded parts of fishing equipment, because they are subjected to large tensile and gliding stresses. The device includes a two-part housing in which there is the hollow cylinder on which the reinforced lower part of the line is wound by a blade coil spring. In the stage of attracting the fish, the reinforced lower part of the line remains invisible and in the stage of swallowing, tearing and pulling the bait with the device, reinforced lower part of the line is pulled out of the device. The pulled out, reinforced lower part of the line cannot be bitten through or torn off by the fish, that enables the reliable catch. The device is used as the bait and model or insert for natural and artificial fishing baits for fishing predatory freshwater and sea fish.

In a method of forming a hole on a work piece, a laser beam is directed from a laser head to a predetermined portion of the work piece to form a pilot hole having a first surface condition, and then the predetermined portion of the work piece is punched using a die and a punch having a cross-section greater than a cross-section of the pilot hole. Thus, a finished hole having a cross-section greater than the cross-section of the pilot hole is formed over the pilot hole. The finished hole has a second surface condition, and the second surface condition is formed by transforming the first surface condition by the punch to have a precise dimension.

The invention relates to a method, a computer program and a rolling mill train for cold rolling a metal strip (200). In order to achieve a shortening of undesired off-gauge lengths, the method according to the invention provides that the head (210) of the metal strip (200) already undergoes a thickness reduction at the first active rolling stand (n) in the rolling mill train, and then is transported on to the next rolling stand, in order to undergo a further thickness reduction there. The method according to the invention also provides for further reducing the initial pass thickness at the n-th rolling stand in accordance with the tensile stress that has built up in the meantime between the n+1-th and the n-th rolling stand.
