摘要： PROBLEM TO BE SOLVED: To provide a cam having a good response in accordance with the full length of a sensor portion in a seaming machine in order to make an airtight capability of a closed can better. SOLUTION: In a ring-shaped driving cam 1 for seaming, an outer contour having an upward ramp 3 and a downward ramp 5 is formed on one side of its operating portion 2, and an inner contour parting a flat region 10 between two deep concave spots 6 is also formed on another side of its operating portion 2. A load cell 13 is maintained by an adjustable supporting portion 14 against the flat region 10. An electrical output signal of the load cell is processed by an analyzing device. When the cam is applying force to a driving follower rotating along with the cam, a signal representing the force is caused to be produced.

摘要： PURPOSE:To prevent the looseness of a channel formed by bringing both turn-back parts to caulking junction by forming a cross section of a base part of the channel to an inverted V-shape, and also, forming a projecting part in both ends in the groove width direction, pressing it against the turn-back parts of opposed plates and bringing both the turn-back parts to plastic deformation by the channel. CONSTITUTION:A channel 2 is inserted between pressing members E1, E2 and attracted and held by a magnet 0, and also, turn-back parts 4, 4 of plates 1, 1 are opposed to each other in a V-shape and inserted into a groove of the channel 2. Subsequently, by the pressing members E1, E2, peripheral parts 2a, 2b of the channel 2 are brought to plastic deformation to a state that they go into the back sides of the turn-back parts 4, 4 and the channel 2 is engaged to both the turn-back parts 4, 4 and the channel 2 is engaged to both the turn-back parts 4, 4. Next, the outside surface of an inverted V-shape base part 2b of the channel 2 and the inside surface of the plates 1,1 are inserted and held by other pressing members P1, P2, and the base part 2b is pressed from the inside and the outside directions. In this case, the pressing member P1 comes into contact with projecting parts 2c, 2c of both sides in the groove width direction of the base part 2b and presses them. Thereafter, both the turn-back parts 4, 4 are brought to plastic deformation to an inserted and pressed state by the peripheral part 2a and the base member 2b, and the plates 1, 1 are brought to caulking junction.

摘要： PURPOSE:To improve safety and to attain labor saving by attracting and holding half bodies of a can drum by attractive poles to a working part where two paris of dies are provided face to face with other and caulking lock-seaming parts on both sides at the same time. CONSTITUTION:When the half bodies 29 of a can drum are supplied from both sides along guide plates 13, 14, the half bodies come in contact with movable dies 2, 3 and the bended edge parts 29a, 29b come in contact and make an engagement with fixed dies 7, 8. The attractive poles 11, 12 attract and stabilize the half bodies 29 of the can drum. A cam member 19 is raised, the movable dies 2, 3 are expanded, the bended edge parts 29a, 29b are caulked at the same time to connect the can drum 29. The cam member 19 falls and the movable dies 2, 3 are retracted by springs 5, 6 to finish the operation. Caulking can be carried out on both sides at the same time, the operating efficiency is improved, handling method need not be changed for materials to be worked and the operation is safe.
