A gripper tape drive device for a shuttleless loom, in which a circular disc is mounted coaxial but not perpendicular to the main loom shaft, its outer circular edge rotatably engaging a circular collar, of which two opposing pins spaced 180.degree. apart cooperate with the ends of a fork rigid with the control shaft of the gripper tape sprocket. Adjustment means are also provided for varying the amplitude of the oscillatory motion of said control shaft.

Hydraulic-exchange pumping device comprising two containers or tanks, inside each of which there are defined: a chamber for the product to be pumped, which is respectively connected, through a delivery valve and a suction valve, to the lines of delivery and of intake of the product to be pumped, as well as a chamber for the hydraulic drive fluid, which is connected to a pump through a four-way, three-position distribution box. This partitioning is accomplished by means of an internal elastic membrane having a decreasing thickness from the its peripheral edge towards its central zone, which can be also equipped with a strengthening cloth embedded inside it, as well as with a set of metal rings having a cross-section surface area decreasing towards the center of the same membrane.
