Abstract

An instrument for measuring dimensions of a can seam portion including a criterion measuring pin, a linear gauge provided with a measuring spindle which is so supported as to be movable along a straight line L in the direction of approaching said criterion measuring pin and in the direction of leaving said criterion measuring pin, a can cap supporting block, and a can body supporting block. The can cap supporting block holds the can such that the direction of measuring can seaming thickness T coincides with the straight line L so that the inner face of the can seam portion contacts the criterion measuring pin. The can body supporting block holds the can such that the direction for measuring the can seaming width W is identical with the straight line L and the lower face so that the can seam portion contacts the criterion measuring pin.

Dependent claims

An apparatus for measuring the dimensions of a seamed portion of a can, comprising:

a base;
a cap can supporting block disposed on said base, said cap can supporting block including means for supporting a can on an upper surface thereof in a horizontal position of the can for measuring a width dimension of the seamed portion and means for supporting the can in an upright position of the can for measuring a height dimension of the seamed portion;
a measuring pin connected to the upper surface of said cap can supporting block for contacting an inner surface of the seamed portion of the can;
linear gauge means mounted on said base for measuring the dimensions of the seamed portion, said gauge including a measuring spindle movable along a straight line approaching said measuring pin to contact the outer surface of the seam portion thereby measuring the dimensions of the seamed portion of the can between the inner and outer surfaces thereof.
