Abstract
418,322. Seaming; beading. WAGSTAFF, H., 21, Bridgewater Street, Liverpool. June 1, 1933, No. 15782. [Class 83 (iv).] A cover 3 is secured to a container 1 by a roller 16 on the end of an arm 14, which is pivoted to a radial arm 9 rotatable about a pivot 8 on cross-bars 5, 6, which engage the top of the container. The lever 14 is moved to wedge the roller against the container top and is then rotated around the container to effect the joint. The roller may be formed to crimp the material. The arms may be adjustable in length.
