Abstract
Shooting and guide members for a shuttle are arranged in a weaving machine. The shooting member comprises an air pressure source which supplies compressed air to one or more acceleration nozzles. The acceleration nozzle or nozzles are arranged to accommodate the shuttle at the time of shooting and, depending on the compressed-air supply, generating one or more air jets. The shuttle is made with surfaces which can be exposed to the air jets. The nozzle and guide members are arranged so as to guide the shuttle at least at the beginning of its shooting trajectory, when the air jet of the acceleration nozzle are brought into effect.
Claims19
Combination of a shuttle and apparatus for accelerating the shuttle from a first side to a second side of a weaving machine, comprising:
- an air pressure source;
- acceleration nozzles receiving compressed air from the air pressure source, the acceleration nozzles generating at least one air jet and being arranged to receive the shuttle;
- and
- guide members arranged to guide the shuttle at least at a beginning of its movement from the first side to the second side,
- the shuttle having a number of surfaces exposed to the air jets.
A combination of a shuttle and apparatus for guiding the shuttle in a weaving machine, from a first side to a second side of the weaving machine, the shuttle defining a guide recess therein, the guide recess extending along a longitudinal direction of the shuttle, the guide recess being open radially outwardly through a slot, the apparatus comprising:
- a numbers of pin-shaped elements, each including a circular disc or sphere arranged one after another in a width direction of the weaving machine, said disc or sphere having a guiding, outer surface cooperating with an inner surface in the shuttle;
- and
- support members arranged on one end of the pin-shaped elements,
- wherein the shuttle runs on the support members as it moves from the first side to the second side, wherein the support members, as the shuttle passes, extend into the shuttle via the slot to guide the shuttle and wherein the support members have a substantially circular shape corresponding to a contour of the guide recess.
An acceleration apparatus for accelerating a shuttle in a weaving machine, the apparatus comprising:
- an acceleration nozzle comprising:
- a body having first and second ends, the body having an opening at the first end and defining therein a recess adapted to receive the shuttle, the opening communicating with the recess;
- at least one first fluid passage extending longitudinally through the body, along the recess;
- a plurality of outlet holes arranged one after another along the first fluid passage, the outlet holes providing a passage way from the first fluid passage to the recess;
- and
- a second fluid passage arranged at the second end of the body and communicating with the recess;
- and
- an air pressure source connected at the second end of the body via a connection member, the air pressure source providing air to the first and second fluid passages whereby air jets into the recess are generated.
A shuttle comprising:
- a body defining a guide recess therein, the guide recess extending in a longitudinal direction of the shuttle, the guide recess being open radially outward via a slot;
- and
- a number of fins arranged on the body.
