  • the rotary frame 4 is rotated by the electric motor 6, the support post 9 is rotated, causing the film roll (b) on the carriage 13 and the stretching roller device (g) to be also rotated around the load (c) as shown in Figs.
  • the film (e) is wound to the load (c) while stretched.
  • the carriage 13 is reciprocated vertically along the post 9 by the chain 12 which is rotated by the motor 6'.
  • the all of the sides of the load (c) is wrapped by the film (e).
  • the film (e) which has wrapped the load is cut by the cutting device (d) on the rotary frame 4 so that the wrapping operation is completed.
  • the support post portion is rotated around the supported load as an alternative to the structure in which the load is rotated. Then, the stretchable film is drawn out from the film roll held by the rotating support post portion through the stretching roller device so as to wrap the load. Therefore, the wrapping operation can be preferably conducted regardless of the weight of the load. Therefore, with the apparatus according to the present invention, energy can be significantly saved with respect to the conventional mechanism in which the load is rotated. Furthermore, weight and the size of the apparatus according to the present invention can be reduced since operating energy to be supplied thereto is transmitted through energy supply means such as a power transmitting cable or the like which is arranged in the hollow stationary shaft.
  • energy supply means such as a power transmitting cable or the like which is arranged in the hollow stationary shaft.
  • the apparatus can be transported to the desired place by, for example, 2-ton track.
  • the load itself does not rotate, no centrifugal force is generated. Therefore, no conventional plate for pressing the load downward is necessary.
  • the loads can be protected from falling down due to the rotation. Therefore, a variety of wrapping operations can be conducted.

Abstract

Une structure rotative (4), comportant un montant de support vertical (9) au niveau de sa partie d'extrémité frontale, est maintenue sur un arbre vertical fixe (2) de façon à pouvoir tourner autour dudit arbre, et un cylindre (g) servant à tendre un film, utilisé pour tendre un film en plastique destiné à être enroulé tendu autour d'une charge (C), est placé sur le montant de support (9). On enroule un film tendu (e) autour de la charge (C) en faisant tourner la structure rotative (4) autour de l'axe de l'arbre vertical fixe (2). Dès lors que la charge (C) n'est pas mise en rotation pendant l'opération d'enroulement du film, elle ne bascule pas étant donné l'absence de force centrifuge.
