The term GATHER INTO A BUNDLE can be summarized by the 6-letter word 'sheave'. Sheaves are a type of pulley used to gather and lift objects, such as rope or cable. They are typically composed of a wheel with a groove in its circumference that is used to hold the rope or cable. The sheave is connected to a frame, which is then attached to a hoist or other lifting device. By using a sheave, multiple strands of rope or cable can be gathered into a single bundle, making it easier to lift and move the object.
