ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a device for improving the attachment of feeders in a circular machine used in manufacturing striped knitted fabrics.
DESCRIPTION OF THE RELATED ART
The systems employed in the past are highly varied, depending on the shape of the feeder and, according to the mechanism on which they are attached, either the structure of the machine or the cross section of the body. But, in almost all known systems, a guide system for the feeder is used, as well as a locking device that uses a screw, which then requires the use of some tool for the purpose of assembling or disassembling the feeder.
Another inconvenience inherent in the known systems is represented by the fact that, once the feeder is released from the machine, it must be moved away from it since it is no longer supported on any fixed part of the machine. Because of this, the threads must usually be released from the feeder, which requires, once again, lining up all the feeders that had been removed from the machine, all of which represents a considerable loss of time.
These inconveniences are further aggravated especially in machines that have mechanisms in the posterior part of the feeders; this may presumably be a very great inconvenience in machines that require handling or manual preparation by the operator in these areas. This happens in double-lined machines where a needle plate is arranged with manually programmable levers.
SUMMARY OF THE INVENTION
The purpose of this invention is to eliminate all of these inconveniences; the feeder can thus be fixed and unlocked without the use of tools. In addition, the system makes it possible to raise the feeder up to a position where the operator can obtain access to the interior part of the machine without either having to cut the threads, or to move the feeder away from the machine.
According to the system involved in the invention, a joint is placed between the upper and outer part of the feeder and the fixed part of the machine so that the feeder may be turned between a working position, situated toward the interior of the machine, and a position situated toward the exterior of the machine, outside the working area, thus leaving the interior part of the machine accessible.
In this way, one gets a very advantageous system for applique machines because of the savings in time and work that it provides in the handling operations that must be performed in the interior mechanisms of the pertinent machine, thus resulting in this preferred applique system for use on machines for which it is intended.
