According to the invention of stretch wrapping machine, a dispenser is rotatably placed on the body for dispensing stretch wrapping material. As displayed in FIGS. 2 and 1, a dispenser 54 is installed on a rotary arm 56 using a first portion 74 protected to the having fellow member 46 in the connection 38, and a 2nd section 76 positioning the dispenser 54. The initial section 74 from the left arm 56 is fitted by means of seat associates 58 around the secondly band 50 in the showing member 46 so as to be rotatable in regards to the up and down increasing axis of rotation 52.

As largely embodied in FIGS. 2 and 1, a motor unit 62 is supplied for driving a car the rotary left arm 56 concerning the axis of rotation 52. Procedure of your motor unit 62 may be aimed by any suitable system, such as a automated logic control or possibly a central processing unit housed in a control pack 64. The output of the motor 62 may be coupled for the rotary left arm 56 by gears, a chain, a belt, a motivated tire, or any other suitable device. As displayed in FIG. 2, the engine 56 pushes a push pulley 66 by means of products pack 68. The generate pulley 66 hard disks a travel buckle 70 that stretches around the next engagement ring 50 of your showing participant 46 and in between two nip rollers 72.
