In an excellent embodiment, the film online 512 might include stretch place packaging material. However, it should be understood that various other packaging materials such as netting, strapping, banding, or tape may be used as well. As used herein, the terms “packaging material,” “web,” “film,” and “packaging material web” may be used interchangeably.
As embodied and shown in Figs. 10-20, a clamp signifies might include a clamping and closing unit 526. The clamping and sealing unit 526 could include a clamp set up 528 having first and second longitudinally increasing clamp participants 530 and 532, a clamping of horizontal wrapper and securing assistance frame 534, plus a linear displaying set up 536. The 1st longitudinally increasing clamp associate 530 could include a vacuum pub 538, proven in more detail in Figs. and 12, and 15-20. The vacuum bar 538 is operatively linked to a vacuum mechanism 540. The next longitudinally increasing clamp member 532 may possibly lengthen typically parallel on the longitudinal level of very first longitudinally stretching clamp participant 530. As displayed in detail in Figs. 12-16 and 14-20, the second longitudinally extending clamp member 532 can include a front side aspect 542, cutting device 544, belt construction 546, leading device 548, foundation curler 550, and/or closing set up 552. The clamping of horizontal stretch wrapping machine and sealing help structure 534 could include the first actuation device 554 as well as a next actuation process 556, configured to selectively expand and retract the first and second longitudinally stretching out clamp people 532 and 530. Moreover or additionally, the foremost and 2nd actuation mechanism 556 and 554 can be mounted on a area of the non-revolving body 516.
The second and first actuation process 554 and 556 could include, for instance, rodless cylinders, piston-cylinder agreements, pulley methods, other purpose methods identified in the art work, as well as perfect combinations thereof. The first and second actuation process 556 and 554 might be installed on the clamping and sealing assistance structure 534 for movement therewith.
