The present disclosure relates to a garbage bin, a bin lid, and an automatic cutting mechanism, wherein the cutting drive device drives the first cutting assembly to move along the first guiding assembly and drives the second cutting assembly to move along the second guiding assembly; the first cutting assembly and the second cutting assembly are approached and moved away from each other when moving back and forth. When approaching to each other, a twisted seal at the upper end of the garbage bag is clamped and cut, and after moving away from each other, a space is left for the new garbage bag at the upper end to expand downwards. The automatic cutting mechanism clamps the twisted seal, a size required to be heated is short, the required heat is little, the heating block and power consumption are low, thus the environmental protection is improved.

A cutting mechanism includes electrodes that are utilized to cut or score a non-conductive outer material of a filament or sheet. The electrodes contact a conductive reinforcing material of the filament or sheet to complete an electric circuit. Electric current flows through and heats the conductive material to oxidize or otherwise separate/cut the conductive material and any remaining non-conductive material.

A hot knife apparatus for cutting tubular webbing. The hot knife includes an anvil having a surface for cutting a tubular webbing, and a hot knife positioned above the anvil adapted to cut the tubular webbing on the surface of the anvil. The anvil has a first slope on an input side of the apparatus and a second slope on an output side of the apparatus. A pair of spreaders is positioned adjacent to the first slope and the second slope for applying tension to the tubular webbing.

A method and a system for manufacturing a mold for creation of complex objects by controlling and moving two end effectors of a robotic system is provided. The two end effectors have a flexible cutting element attached to, and extending between, the two end effectors. The method includes the steps of: defining at least one surface representing the inner surface of the mold; dividing the surface into a number of segments represented by planar curves on the surface; for each planar curve, calculating at least one elastic curve representing the planar curve; for each calculated elastic curve, calculating a set of data corresponding to placement and direction of the two end effectors for configuring the flexible cutting element to a shape corresponding to the calculated elastic curve; and sequentially positioning the end effectors according to each set of data. The flexible cutting element thereby cuts the mold from a block.
