Problem statement on Machine Technical elements. The changes made to the bottling line have had a significant impact on its performance. The removal of the huge accumulator before the labeller resulted in the loss of some accumulation time, which may have affected the overall efficiency of the line.

The switch from a $3-$lane packer with a combiner to a $2-$lane six$-$packer may also have caused some disruption in the packing process, leading to reduced productivity.

The switch from ACL to PSL with the same line ratings may have resulted in some improvements in the line's overall performance, but further analysis is required to determine the exact impact of this change.

The introduction of a tax stamp to the labelling process requires a third line printing, which may have caused the printer to struggle at higher speeds, resulting in reduced productivity. The decision to reduce the labeller speed to $52,000$ bottles per hour to maintain good quality printing is a significant cause for concern.

This reduction in speed may result in reduced productivity and efficiency, and further analysis is required to determine the best way forward.

The supplier's relook at the printer settings is a positive step towards improving the line's productivity, and it is essential to identify the best recommended speed for the third line printing.

The comparison between the line $3$ ratings and the line $5$ ratings is interesting, but a detailed analysis of the factors that contribute to the difference in ratings is required to determine the best way forward.

Final answer: Overall, the changes made to the bottling line have had a significant impact on its performance, and further analysis is required to determine the best way forward. The reduction in speed and the introduction of a tax stamp have resulted in reduced productivity and efficiency, and the line's overall performance needs to be carefully monitored to ensure that it meets the required standards.
