The grooves on the pulley wheel
The middle part of a pulley is called the wheel or sheave. It is the round component that rotates on an axle and around which the belt or rope travels. The wheel is typically grooved to keep the belt or rope in place and provide a better grip for transmitting force.

A rope goes over the wheel of a pulley and can also be threaded through the grooves to increase friction and grip. The way the rope is positioned on the pulley determines how it will interact with the load being lifted.
A flagpole can be considered a simple pulley system because the rope attached to the flag acts as a type of pulley, allowing the flag to be raised and lowered by pulling on the rope. This system demonstrates how pulleys can be used to change the direction of force to make lifting and lowering objects easier.

A pulley doesn't raise or hoist sails. A pulley is just a wheel that eases a change in direction of a rope. It is a rope that hoists or raises sails. A rope for this purpose is called a Halyard.
This is called a pulley.
Rope and pulley.
A sheave or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. The sheave spins on an axle or bearing inside the frame of the pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. (A sheave is actually part of the pulley system.)
A sheave (/ʃiːv/) or pulley wheel is a grooved wheel often used for holding a belt, wire rope, or rope and incorporated into a pulley. This allows the wire or rope to move freely, minimizing friction and wear on the cable. Sheaves can be used to redirect a cable or rope, lift loads, and transmit power. A sheave (pronounced “shiv”) is actually part of the pulley system. The sheave is the rotating, grooved wheel inside the pulley.
