If the spinner is forced to use such an inadequate machine, which is in principle superfluous, then it should at least provide the optimum in operating capacity. Even in this respect, however, the roving frame still leaves room for improvement. The efforts of machine manufacturers should be directed toward the following aspects:
- design of simpler machines, less liable to faults;
- increase in spindle rotation speeds;
- larger packages;
- automation of the machine and of package transport.
These improvements must be achieved without any increase in production costs for the spinner.
