Abstract
In a needle loom having at least one needle bar coupled by cam follower means to two eccentric shafts in order to be moved by said eccentric shafts in a movement path having two components which are normal to one another, the eccentric shafts are each provided with eccentric cams which have equal amounts of eccentricity and are adapted to be synchronously rotated, and said cam followers rotatably mounted on said eccentric cams are movably connected to one another by at least one coupling element which is adapted to yield in one direction but is stiff in a direction normal thereto.
Claims25
A needle loom having at least one needle bar coupled by cam and follower means to two eccentric shafts in order to be moved by said eccentric shafts in a movement path having two components which are normal to one another, wherein said eccentric shafts are each provided with eccentric cams which have equal amounts of eccentricity and equal angular positions of rotation and are adapted to be synchronously rotated, and cam followers each rotatably mounted on said eccentric cams are movably connected to one another by at least one coupling element which is adapted to yield in one direction but is stiff in a direction normal thereto.
