Abstract
The movable brake shoe of the projectile brake is controlled by a wedge shaped adjusting member. A servomotor and spindle arrangement are used to move the adjusting member so as to adjust the position of a slider which, in turn, serves to adjust the amount of movement of the movable brake shoe towards the stationary brake shoe during a braking operation.
Claims4
A projectile brake for a weaving machine comprising
- a stationary brake shoe;
- a movable brake shoe disposed in spaced facing relation to said stationary brake shoe to brake a projectile therebetween;
- a reciprocally mounted slider;
- a linkage connecting said slider with said movable brake shoe;
- a brake lever for actuating said linkage to move said movable brake shoe relative to said slider and to said stationary brake shoe;
- a wedge-shaped adjusting member disposed in slidable relation with said slider;
- means for moving said adjusting member to effect movement of said slider whereby movement of said movable brake shoe towards said stationary brake shoe is adjustable to vary a braking effect therebetween said means including a threaded spindle rotatably secured in said adjusting member and a servomotor for rotating said spindle to move said adjusting element relative to said slider;
- at least one sensor adjacent said brake shoes to detect the presence of a braked projectile thereat and to emit a signal in response thereto;
- and
- a control device connected to and between said sensor and said servomotor to actuate said servomotor in response to a signal from said sensor to move said adjusting member in a predetermined direction.

A projectile brake for a weaving machine comprising
- a first brake shoe;
- a movable brake shoe disposed in spaced facing relation to said first brake shoe to brake a projectile therebetween;
- a reciprocally mounted slider;
- a linkage connecting said slider with said movable brake shoe;
- a brake lever for actuating said linkage to move said movable brake shoe relative to said slider and to said first brake shoe;
- a wedge-shaped adjusting member disposed in slidable relation with said slider;
- means for moving said adjusting member to effect movement of said slider whereby movement of said movable brake shoe relative to said first brake shoe is adjustable to vary a breaking effect therebetween;
- at least one sensor adjacent said brake shoes to detect the presence of a braked projectile thereat and to emit a signal in response thereto;
- and
- a control device connected to and between said sensor and said means to actuate said means in response to a signal from said sensor to move said adjusting member in a predetermined direction.
