Abstract
A process for introducing a fiber sliver into a fiber processing machine which has an openable sliver feeding device and a sliver introduction funnel and a sliver injector, comprising the following steps: opening the openable sliver feeding device, grasping the leading end of the sliver pneumatically into and through the sliver introduction funnel and into the opened feeding device and closing the sliver feeding device on the sliver. The invention also includes a device for carrying out the process.
Claims31
A process for introducing a fiber sliver into a fiber processing machine which has an openable sliver feeding device and a sliver introduction funnel, comprising the following steps:
- (a) locating a travelling sliver injector device in front of said fiber processing machine;
- (b) opening said openable sliver feeding device with said sliver injector device;
- (c) configuring said sliver injector device into contact with said sliver introduction funnel so as to define a sliver feeding channel therewith;
- (d) grasping a leading end of said sliver and conveying the sliver end into the sliver injector;
- (e) pneumatically conveying said leading end of said sliver into and through said sliver feeding channel and said sliver introduction funnel and into said opened feeding device;
- and
- (f) closing said sliver feeding device on said sliver.
A device for introducing a fiber sliver to a fiber processing machine which has an openable sliver feeding device and a sliver introduction funnel, comprising:
- (a) a sliver injector adapted to pneumatically introduce a sliver into said funnel, said injector disposed to contact said funnel and to form a pneumatic sliver feeding chamber with said funnel;
- (b) compressed air means disposed in said injector for directing a stream of compressed air into said pneumatic chamber in a direction to convey said sliver into said feeding device;
- and
- (c) said injector defining a control device configured to open said feeding device prior to directing said stream of compressed air into said pneumatic chamber said air of compressed air stream being directed into said pneumatic chamber to convey the leading end of said sliver into said feeding device.
A travelling automatic service unit configured to travel along a fiber processing machine to carry out various functions at spinning stations of the processing machine, said service unit further comprising:
- a device for introducing a fiber sliver to said spinning stations which have an openable sliver feeding device and a sliver introduction funnel, said device further comprising
- (a) a sliver injector adapted to pneumatically introduce a sliver into said funnel;
- (b) compressed air means disposed in said injector for directing a stream of compressed air into said funnel in a direction to convey said sliver into said feeding device;
- and
- (c) a control device configured to open said feeding device prior to directing said stream of compressed air into said funnel said control device being operably configured with said sliver injector.
