| 20120124944 | Wrapping Apparatus And Method Including Metered Pre-Stretch Film Delivery Assembly - A method and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material based upon load girth is disclosed. A non-rotating ring carries a belt driven by a motor. A packaging material dispenser is mounted on a rotating ring, and the rotating ring may include a pulley that connects to the band, such that the rotating ring is driven by the drive belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for at least a portion of a revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum packaging material use is obtained by dispensing a length of pre-stretched packaging material that is between approximately 90% and approximately 120% of load girth. Once the amount of packaging material to be dispensed per revolution is determined, a ratio of rotating ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution/rotating ring rotation) can be set and mechanically controlled. Thus, for each revolution of the rotating ring and dispenser, an amount of packaging material is dispensed and wrapped around the load. In an alternative embodiment, the ratio is electronically controlled. | 05-24-2012 |
| 20120102887 | Machine Generated Wrap Data - A method for generating data with a wrapping machine during wrapping of a load includes measuring a length of packaging material dispensed during wrapping of the load with a sensing assembly on the wrapping machine. The method further includes obtaining a value indicative of a weight of the packaging material per unit of length and determining a weight of the packaging material dispensed on the wrapped load based on the measured length and the obtained value without removing the packaging material from the load. The determined weight of the packaging material is displayed on a display device. | 05-03-2012 |
| 20120102886 | Methods and Apparatus For Evaluating Packaging Materials And Determining Wrap Settings For Wrapping Machines - A method of determining a wrap force or payout percentage at which to wrap a load with packaging material may include dispensing packaging material. The method may also include forming a tear in a portion of the packaging material. The method may further include identifying a first payout percentage at which the tear exhibits a first behavior. The method may also include identifying a second payout percentage at which the tear exhibits a second behavior. The method may further include selecting a third payout percentage between the first payout percentage and the second payout percentage, for wrapping the load. | 05-03-2012 |
| 20120102881 | Bladder Clamp And Related Methods And Apparatus For Wrapping Loads - A clamp assembly may include a first jaw member which may have a selectively inflatable bladder. In addition, the clamp assembly may further include a second jaw member which may have a belt. The first jaw member and the second jaw member may be configured to clamp material between the selectively inflatable bladder and the belt. | 05-03-2012 |
| 20090049803 | SIDE SEAL ASSEMBLY WITH INDEXING MECHANISM - A side seal assembly for a shrink wrap packaging system is located downstream in the feed direction from a wrapping station to join first and second plies together and enclose each of the products in individually wrapped packages. The side seal assembly includes a heated side seal mechanism to form the side seal weld and separate the selvage film. The assembly includes an indexing mechanism to index the side seal mechanism and expose a clean surface to the film without removal or extensive servicing of the assembly and the heretofore requisite downtime for the system. The sealing and cutting functions are combined into a single, stationary component thereby reducing the number of movable parts. Moreover, indexing the side seal mechanism operatively exposes a clean, free of resin build-up, peripheral edge of the side seal mechanism to the plies, without the need to stop production for extended periods of time while consistently producing a thin side seal weld on the package. | 02-26-2009 |
