The job was to put the box of "cops" (Note-trade term for wound bobbins)
With the correct grade and count number in the Holder/rack above the Battery...Inserting them into the Battery magazine was the weavers job and until the Automatic loaders and winders came in with modern machinery(late 60's) The Battery filler job was then changed to a Weft-man Loading "Cheeses" of weft which reduced the Attention need to keep the supply going
Depending on the Count being woven a bobbin could last a Minute or 5 minutes and the Magazine needed constant Monitoring as well as the Other things to do with that loom and 1 weaver could have half a dozen to check at the same time

Where I worked and they had the latest machines with the weft-winders ect 1 weaver had 16 looms to mind
And I looked after 16 looms also to clean ,patrol grease them as well as 3 other sets in the group (48 looms) as well as myother dutie of taking cloth off loom ,cleaning greasing looms at Warp changes (varied daily)
Also brushing up (best job on the Shift!)

Proud to say we had the Best productivity in the whole Mill ...and the number of my group...
13 
There were about 1500 looms in the waeving shed where I worked Noisy?... 95-100 Decibels at 10 yards And I'd be working 2 ft away from Any
Picking stick noise and there'd be several hundred all running in the same area
If you get a chance to see a powerloom in action Its well worth the experience
What I've said here is only part of the Jobs that keep this machine running the weaver is one small part os the Process...
And I'm not counting the Yarn preparation nor Cloth finishing part of the Process
