Abstract
A heald control system has a heald rod which is reciprocated along its longitudinal axis and has a resiliently deflectable body portion formed from a magnetically attractable material and a retention latch formation. During reciprocation, the heald rod is moved along a path of travel between first and second limits in a first zone where the body portion normally travels in a undeflected position and in a second zone where the body portion travels in a deflected position. A fixed cam is engageable with a cam on said body portion during the reciprocation to cause the body portion to move from the non-deflected to the deflected position during travel from the first zone into the second zone. A fixed latch is located to one side of the first zone of the path of travel to engage the latch formation only when the body portion is in said deflected position. An electromagnet is located adjacent said path of travel of the body portion when it is in its deflected position, so that the electromagnet when energized is capable of holding the body portion in the deflected position as the latch formation moves from the second zone and into registry with the fixed latch to cause the latch formatio…
