[0041] The function of the light strip pay-off rack is to release the soft circuit board with the LED soldered on at a uniform speed during the production process.

[0042] The straightening machine support provides unstraightened shaped metal strips for the production process and transfers the shaped metal strips to the metal straightening machine for straightening.
