Abstract: The present invention relates to a bicycle driving apparatus, and more particularly, to a bicycle driving apparatus which enables the forward travel of the bicycle regardless of the forward rotation or reverse rotation of the pedals. The bicycle driving apparatus according to the present invention enables a bicycle to travel in the forward direction not only when a pedal rotates in the forward direction but also when the pedal rotates in the reverse direction.

Abstract: An extrusion molding apparatus for forming a product having an extrusion molding. The extrusion molding apparatus includes an extruder extruding the product through a die installed at an outlet of the extruder. A second inlet is formed at one side of the die to receive a second synthetic resin. A second extruder feeds the second synthetic resin into the second inlet and a passage in fluid communication with the second inlet. The passage transports the second synthetic resin to nozzle grooves formed in the die, thereby coating the second synthetic resin on a surface of the product extruded from the die having a first synthetic resin.
