As outlined by the principal exclusive horizontal stretch wrapping machine

42, electric motor output shaft 46, bevel gears 48,52, and powered shaft 50, rotation of the rotational or orbiting increase associate 30 around the axis 34 can cause the stretch film roll carriage construction cable 68 being injury throughout the drum part 56 from the cord drum assembly 55. In this way, as being the rotational or orbiting boom participant 30 is constantly rotated, the stretch film roll carriage construction 38 will in effect be consistently dragged upwardly by which stretch film from the stretch film roll fitted upon the stretch film roll carriage assemblage 38 will be continuously dispensed and wrapped round the palletized package, product and load or report 12 disposed at the wrapping station 14 in a vertically stretching out spiral-wrap collection.

With reference ongoing being made to Numbers 2a,2b,3, and 4, so when might greatest be loved from Body 2b, some solenoid units 76,78 are fixedly attached with individual opposite aspects in the static thrive participant 28 through suitable installing brackets 80,82. As is well known, each one of the solenoid devices 76,78 comprises a body portion 84,86 and a plunger mechanism 88,90, and the solenoid devices 76,78 are constructed in such a manner that the actuated stroke of the respective plunger mechanisms 88,90 of the two solenoid devices 76,78 are different, that is, for example, the stroke of the plunger mechanism 90 of the solenoid device 78 is longer than the stroke of the plunger mechanism 88 of solenoid device 76. Moreover, the less end section of every single plunger mechanism 88,90 from the solenoid units 76,78 is modified to operatively interact with a diametrically reverse upper surface area part of the upper flanged associate 58 of the cable tv drum assemblage 55 when in simple fact a selected one of several solenoid devices 76,78 is actuated. As can therefore be appreciated from a comparison between FIGURES 2a,3, and 4, when neither one of the solenoid devices 76,78 is actuated, the plunger mechanisms 88,90 of the solenoid devices 76,78 are disengaged from the upper surface portion of the upper flanged member 58 of the cable drum assembly 55 and the coil spring 72, fixedly mounted upon the rotational or orbiting boom member 30 and engaged with the undersurface of the lower flanged member 60 of the cable drum assembly 55, will cause the cable drum assembly 55 to be moved to its uppermost vertical position such that the detent pins 62 of the upper flanged member 58 of the cable drum assembly 55 will be disposed within the recesses 64 formed within the lower surface portion of the static boom member 28 whereupon the cable drum assembly 55 is effectively rotationally locked to the static boom member 28 as has been discussed hereinbefore. , as has been discussed hereinbefore, because the rotational or orbiting increase fellow member 30 is consistently rotated, the stretch film roll carriage assemblage 38 will in effect be constantly drawn upwardly by which stretch film from the stretch film roll attached on the stretch film roll carriage construction 38 will be constantly dispensed and twisted throughout the palletized product, load and package or post 12 disposed at the wrapping station 14 in a vertically stretching spiral-wrap range.again and Accordingly
