Abstract
Abstract Method and apparatus for continuous chromium electroplating of bars; bars are mechanically and electrically connected in an uninterrupted row, which is rotated and advanced along a straight path through an anode immersed within an electroplating bath. The bar surfaces, in the course section crossing the electroplating anode, are brushed clean by means of a stationary brushing device, acting on rotations bars.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A method for electroplating metal bars which comprises: mechanically and electrically connecting said bars to form an uninterrupted row, immersing in an electroplating bath an anode means adapted to substantially surround at least a portion of a bar while being spaced therefrom, said anode means having a longitudinal slot therein, mounting a stationary brush means in said slot adapted to contact a bar in the anode means, passing the bars through the anode means in a straight path while rotating the bars about their longitudinal axes, and concurrently slideably forcing said stationary brush means against the bar, whereby the bar surface is continuously cleaned by a brushing action during electroplating.
Claim 2
Independent Claim
110 words
A method for electroplating metal bars which comprises: mechanically and electrically connecting said bars to form an uninterrupted row, immersing in an electroplating bath an anode means adapted to substantially surround at least a portion of a bar while being spaced therefrom, said anode means having a longitudinal slot therein, mounting a stationary brush means in said slot adapted to contact a bar in the anode means, passing the bars through the anode means in a straight path while rotating the bars about their longitudinal axes, and concurrently slideably forcing said stationary brush means against the bar, whereby the bar surface is continuously cleaned by a brushing action during electroplating.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein the brushing action is performed along the generatrix of a bar surface within the anode means.
Claim 4
Dependent Claim
15 words
The method of claim 1 wherein a constant pressure is applied to the brush means.
Claim 5
Dependent Claim
19 words
The method of claim 2 wherein the brush means is forced against the bar surface in a radial direction.
Claim 6
Dependent Claim
22 words
The method of claim 1 wherein the electroplating bath is a chromium electroplating bath and the anode is a chromium electroplating anode.
Claim 7
Dependent Claim
21 words
The method of claim 4 wherein the brushing action by the brush means extends beyond the ends of the anode means.
