An interactive loom, which includes a loom-mechanism, a user interface, a loom interface, and a controller. Each cam is in the form of a cylinder rotating about the axis thereof. The circumferential surface of the cam exhibits a determined surface geometry, such that each of a plurality of sections of said circumferential surface corresponds to a respective one of the arms. The circumferential surface further exhibits a respective cross sectional profile and such that each rotational position of said cam is associated with a respective state of lowered and raised arms. The loom-interface includes a motor coupled with the cam, and operates loom-mechanics according to instructions. The controller receives a design from the user-interface and transforms the design into a sequence of states of the arms required for achieving the design. The controller further provides the instructions to the loom-interface. The instructions are associated with state changes of the arms.

A warp shedding apparatus of a loom includes a plurality healds arranged in a weaving width direction of the loom. Each heald has a thread eyelet through which a ground warp yarn is passed and held. The healds are raised and lowered to form a shed. A difference in tension between raised ground warp yarns and lowered ground warp yarns held by the healds located in opposite end portions in the weaving width direction is greater than a difference in tension between raised ground warp yarns and lowered ground warp yarns held by the healds located in a central portion in the weaving width direction.
