A crank-type drive device for a loom including a crank hub non-rotatably attached to a drive shaft, a holder non-rotatably attached to the crank hub, an eccentric shaft supported by the holder, and a connecting member rotatably supported by the holder via the eccentric shaft and a bearing and connected to a drive target member of a loom. The crank hub includes a plate-shaped attaching part which an attached surface of the holder is attached thereto and has an attaching surface in contact with the attached surface, and a fixing mechanism for fixing the crank hub to the drive shaft, the drive shaft being inserted and fitted in the fixing mechanism. The crank hub is configured so that the fixing mechanism is positioned on the attaching surface-side of the attaching part in a plate thickness direction.

A loom includes a pair of side frames configured to support a beating device and each having a beam support configured to support a warp beam; and a drive mechanism configured to rotationally drive the warp beam including a beam gear, where each of the side frames is configured by a main body frame configured to support the beating device and a let-off frame fixed to the main body frame and configured to support the beam support. The drive mechanism is attached to the main body frame.

A loom including a drive transmission shaft connected to a warp beam via a gear member inside a loom frame and inserted in a through-hole formed in a side frame, and a support structure for supporting the drive transmission shaft, the support structure including a first bearing and a second hearing externally fitted to the drive transmission shaft at an interval in an axis line direction. The support structure includes a first bearing case configured to accommodate therein the first bearing and attached to the side frame inside the loom frame and a second bearing case configured to accommodate therein the second bearing and attached to the side frame outside the loom frame.

Systems and methods for automatically producing a cord structure are provided herein. In one embodiment, a method comprises automatically forming, with at least one robotic arm, a first plurality of loops in a first plane, and automatically forming, with the at least one robotic arm, a second plurality of loops in a second plane orthogonal to the first plane, the second plurality of loops slippably engaged with the first plurality of loops. In this way, cord structures may be quickly constructed, thereby reducing labor input and expense.
