The present innovation gives a inexpensive, simple and reliable method of unitizing multiple unit products into a one twisted package by having an overwrap material which should not be properly temperature enclosed.

When the present device is in comparison with other device at present utilized to pack merchandise in corrugated containers and the cost of the corrugated boxes them selves, the creation shows an enormous saving money. The innovation has comparable charges with kraft wrap but it really gives a significantly tighter and better unitized package than that probable with kraft wrap. Together with these aspects the invention can use stretch film, stretch netting material, or stretch fine mesh material which offers item exposure not possible with kraft or corrugated wrapping. The netting and fine mesh features any additional characteristic of making the load “breathe in.” This attribute is extremely desirable when are living generate is shipped and packaged. The present inventive system offers packaging speed, reliability because of the elimination of the package sealing energy and problem savings in that less energy is required to package the product furthermore.

A basic problem with shrink and noncling stretch film packaging is that the primary reliability and strength of the package is determined by the consistent quality of the seal. These closes depend on a cautious upkeep of the closing jaw bone and are never as strong as being the film itself. The time come to create the seals is really a constraining factor about the achievable speeds of many film wrapping systems. Associated troubles are that some stretchable resources, as for instance stretch netting, cannot be heating closed when thin film internet widths used in spiral wrapping should not be effectively heat covered.

In the favored embodiment the present innovation works with a spiral wrapping process to use the film online on the fill.

The application of spiral wrapping machines to wrap a lot is known inside the craft. One particular apparatus is displayed by Usa Pat. No. 3,863,425 where film is led from your roll and wrapped all around a cylindrical fill within a spiral setup. A carriage brings the film roll adjoining the surface of the weight to downpayment an overlapping spiral wrap around the load and returns within the reverse course to put in one more spiral overwrap around the weight. Other spiral wrapping apparatus are explained by United states Pat. Nos. 3,857,486; 3,788,199; 3,549,017; 3,412,524; 3,191,289; and two,716,315. The previously suggested patents count on heating reduce in sizeadhesives and material, a heating seal off or even the tacky the outdoors of your film to hold the outside layer of wrap within a fixed placement.

Various other patents have defined using components for wrapping tons. In United states Pat. No. 3,003,297 a complex holding and cutting device is used to place tape over a pack and cut it off with the process getting recurring for each box. The exclusive function and design from the tying, cutting and clamping mechanisms from the current technology fails to call for a connecting or heating system of your film in order for the system to function.

United states Pat. No. 2,088,133 discloses a turn back wrapping cable entering machine. Inside the reference a gripper process keeps a band constantly in place with regards to the load being twisted plus a rotatable ring generate rotates the music band across the fill until the music group has accomplished more than one wrap from the load and goes by across the body of your gripper device.
