Arpac 737C Manual Shrink Bundler

Automatically Bundle Wrap Intermixed Random Packages

Designed for applications where high speeds are not a requirement, the Arpac 737C is perfectly suited for on-line packaging and off-load production and distribution. Often used as a stand-alone unit, its versatility and mobility makes the 737C ideal when package sizes vary and floor space is limited.

With a straight-through infeed, this manually operated shrink bundler wraps individual and randomly grouped sizes of packages. The 737C accommodates a wide range of product sizes with a 20" seal jaw opening.

The hot knife temperature and film cut-off temperature are independently controlled, ensuring a positive welded bond while producing a seal stronger than the film itself.

This proven sealing system has been used in hundreds of installations worldwide and is part of a long line of industry standard shrink bundlers.

Combined with an ARPAC shrink tunnel, the 737C ensures optimum production efficiency with minimum downtime and maintenance costs.

Mode of Operation

The operator places the manually collated configuration of cartons centered on the infeed table. The operator then manually pushes the product forward into the film web, through the seal frame until the spring-loaded guide on the opposite side of the seal frame pops up. As the product is moved forward the machine detects film usage and starts the powered film unwind feeding film. After enough film is fed, the powered film-unwind system stops. The operator then simultaneously presses the dual palm seal bar start buttons. This activates the seal bars, which close, seal, and cut the film. After the seal dwell timer times out the seal bars reopen. When the next product is advanced the sleeved product is pushed the bundle onto the customer's discharge conveyor.
