Title:
WINDING CORE, WINDING REEL AND BAND-WINDING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/039018
Kind Code:
A1
Abstract:
Provided are a winding core, a winding reel and a band-winding method, which are capable of preventing the band from being easily bent in a certain direction when the band is inclined to generate a difference in winding length, causing strain in winding around the band.
When a carrier tape (10) is traversely wound on a curved peripheral surface (2), the peripheral surface (2) is inclined radially outward with movement from one end section toward the other end section by a cylindrical winding core (1) which overlaps one side section of the carrier tape (10) on the other side section of the wound carrier tape (10) and winds the overlapped carrier tape (10), and an inclination (θ) of the peripheral surface (2) is made to base on 0<θ≤2arctan (the thickness/traverse pitch of the carrier tape). The peripheral surface (2) of the winding core (1) is inclined in the opposite direction from the inclination of the overlapped section of the carrier tape (10), thus making it possible to relax the inclination of the overlapped section of the carrier tape (10).
