FIELD: manufacturing technology.
SUBSTANCE: group of inventions relates to unwinding devices. Coil unwinder for coils with web material contains unwinding stand. Unwinding stand has at least one unwinding element for coil rotation and feeding web material in the direction of the feed path. To lift the spindle of the first free of coil from unwinding stand in extraction position lifting elements are used. For loading the second coil in unwinding stand loading element is used. Clamping element is made with possibility of pressing web material of the first coil being in extraction position to the second coil being in unwinding stand. Clamping element transmits rotation from the second coil to the first coil to create pressure for attachment of the material of the first coil with the material of the second coil. Grip material is performed by means of double-sided adhesive tape.
EFFECT: simple design and possibility of unwinding coils wound in different directions.
