The TB series packaging machine stems from the considerable expertise developed in the valve and open-mouth bagging, and it is placed on the market in order to meet the demands of packaging in polyethylene bag with flat tubular reel formation or with gusset.
All types of solid products – both powders and grains/granules – can be bagged. This machine is very simple and easy to operate; it has heavy-duty frames and members, including protective side panels that can be fully opened, which allow all the machine parts to be easily accessed. It is fitted with a simple and reliable operation system (mechanical main operation controlled by brushless motors) requiring a low maintenance.
The check and replacement of sealing bars of empty and filled bags are easy and fast given their position and the connection through quick couplers. The operation cycle is essentially based on a roll with a pendulum motion that picks up the empty bag and positions it under the filling mouth, then under the final sealing zone.

Models and features
Two different models are constructed: TECNO TB/1 for production rates up to 800/1000 bags per hour and TECNO TB/2 for production rates up to 1200/1400 bags per hour (always depending on the type of product to be packaged) with the possibility of processing bags from a minimum of 5 Kg to a maximum of 50 kg, with the reel having a minimum width of 300 mm and maximum width of 620 mm.
Pneumatically-powered “comb-like” device for cleaning the inside of filled bag before the final sealing. The same “comb-like” device, depending on the type of packaged product, can be used to deaerate the product inside the bag prior to sealing the bag.
Additional frame unit for printing and thermal transfer onto neutral reel with a maximum printing area of mm 300 x 128 of height. Possibility of inkjet marking on stretched film with high-resolution printing.
