A film winding method in which a starter of a film unwound from a tenter is taken up by a take-up machine, and a start-up end of the film taken up by the take-up machine is started to be taken up by a winder. t , the time from cutting the film unwound from the tenter to form the starting end thereof and passing the starting end of the film through the take-up machine and winding the film on the winding machine is t 1 , and within the range of this time t 1 the time puller moves beginning of the film at a speed V c to the winder and t c, the speed of the winder from the wound to the starting end winder of the film and take-up machine stopped kV t ( k is the time induced to accelerated up to a constant) t 2, then the time winder and take-up device maintains the speed kV t t 3, then winding machine and take-up device until the same speed V t and tenter When the time is caused to decelerate and t 4 The V t, V c, k, determined t 1, t c, the t 2, t 4 as a known quantity, the film after forming the starting end to cut fed from the tenter, the winding of the winder the slack amount F t of tenter is feeding the film to the take-up speed of the speed and puller are set to the same speed V t and the tenter is calculated by the following equation (1), the starting end to cut the film fed from the tenter after forming, following the winding length F w of the film winder wound up take-up speed of the take-up speed and puller of the winding machine is set to the same velocity V t and tenter (2 ) was calculated by the equation, F t = F w a becomes t 3 calculated, the known amount V t, V c,
A film winding method characterized by controlling the drive of a winding machine and a winding machine based on k, t 1 , t 2 , t 4 and the calculated amount t 3 . F t = V t (t 1 + t 2 + t 3 + t 4) ... (1) F w = V c t c + kV t t 2/2 + kV t t 3 + (kV t + V t) t 4/2 ... (2 )
