beading-machine

Century Dictionary and Cyclopedia

1. n. In sheet-metal work, a hand- or power-machine for impressing a bead upon tinware, boxes, cans, covers, collars, gutters, and other objects or parts of objects. The essential features of the many forms of beading-machines are the beading-rolls, placed in pairs, one each on two parallel shafts, and turning together, the face of each roll being of some concave or corresponding convex form. The sheet-metal to be beaded is passed between the moving rolls and is impressed with the bead or form of the roll-face. Power-machines, by the use of supplementary parts, may also be used as flanging-, forming-, trimming-, and crimping-machines. See crimper, flanging-machine, and forming-machine.
