Abstract: An automated knotting method for a belt axis bundle includes a belt axis bundle which has an end segment of a thread that is freely extendable and movable. The method is executed by an automated knotting device. The method includes the following steps: forming a first loop with a first part of the end segment; creating a first bent segment with a second part of the end segment and threading the first bent segment through the first loop; twisting the first loop to form a twisted loop; forming a second bent segment with a third part of the end segment and threading the second bent segment through the twisted loop; controlling the second bent segment to rotate around the belt axis bundle and tightening the second bent segment, thereby creating a slip knot that wraps around and is tightened, and is located at an outside of the belt axis bundle.

Abstract: A bag clamping and sealing machine includes a first top bar, a second top bar, a first bottom bar and a second bottom bar movable along a horizontal X-axis. A first top board, a second top board, a first bottom board and a second bottom board movable along a horizontal Y-axis which is perpendicular to the horizontal X-axis. The first top bar and the second top bar, and the first bottom bar and the second bottom bar move toward each other to clamp a bag opening of a bag to be a flattened portion. The first top board and the second top board, and the first bottom board and the second bottom board move toward each other to narrow the flattened portion to be an elongate portion. A robotic arm firmly clamps the elongate portion between a C-clip and an I-bar.
