The apparatus of orbital stretch wrapping machine 8
As embodied herein and demonstrated in orbital stretch wapping machine, a packaging fabric weakener is supplied for weakening the packaging materials 116 involving the stress 124 and the dispenser 102. The packaging materials owner 110 ideally includes a cutter 142. Cutter 142 could include an compared decreasing element, including scissors, or possibly a single reducing factor say for example a razor blade. Cutter 142 is connected to an actuation handle 144 which techniques with jaws 112, 114. Actuation handle 144 is moveable between a cost-free place along with a contact situation. As jaws 112, 114 move along downstream path 152, jaws 112, 114 open, automatically releasing packaging material 116, scooping element 140 moves upward to scoop the lower edge of the web of packaging material 116 into a rope 118, and actuator lever 144 moves from the free position to the contact position. When actuation lever 144 is with the contact place, cutter 142 is activated to weaken packaging fabric 116 by decreasing a minimum of a part of the website of packaging material 116, like the rope 118 of packaging material 116.
The apparatus may include means for securing a trailing end of packaging material to the load, according to one aspect of the present invention. As embodied herein, the means for securing includes a film wipedown mechanism for wiping a film tail onto the load after the packaging material has been cut. As demonstrated in Fig. 1, the film wipedown mechanism 180 involves wash loops 182 and a wipe left arm 184. This enables a film tail to become washed on fill 124 as the packaging material 116 is minimize.
Other cutters and wipedown preparations could also be used.
A method for wrapping a load according to the present invention is shown in Figs. 5 – 11. As displayed in Fig. 5 and according to a preferred embodiment of the present invention, a load 124 is conveyed by a conveyor 118 to a turntable assembly 120 in the wrapping station and load 124 is positioned on top of rotatable turntable 122 of turntable assembly 120. Jaws 112, 114 of packaging substance holder 110 keep a major stop segment 30 of the roped sheet of stretch wrapping packaging materials 116, preferably stretch cover packaging material. Cog 132 is located at a downstream conclusion of packaging material owner 110, and jaws 112, 114 are positioned in the upstream finish of packaging material owner 110, and cam follower 158 is located towards the upstream part of ramp.
