ABSTRACT:
The seaming equipment is used for interlocking and sealing the rim of a can which includes a cylindrical body enclosed at the opposite ends by respective covers. The equipment comprises a single vertical column, rotatable about its own axis; a plurality of spindles carried by the column, disposed substantially in radial formation with axes vertical and operating in conjunction with relative spring-loaded means each serving respectively to support and to clamp together one cover and the relative cylindrical body; entry conveyor means by which the cylindrical bodies and relative covers are caused to enter the column in readiness for seaming operation; exit conveyor means by which the cylindrical bodies and covers are caused to exit the column upon completion of the seaming operations; at least three work stations arranged around the single column and encountered in sequence between the entry conveyor means and the exit conveyor means, through which the spindles and the relative clamping means are rotated by the column, revolving about their respective vertical axes, so as to interlock and compress together the edge of the cover and the lip of the cylindrical body.
