A shrink tunnel for shrinking shrink films on packages includes a transport path that passes through the treatment chamber. Arrays on opposite sides thereof have nozzles for dispensing hot gas. Each array has an associated guide plate and a lifting device for adjusting the guide plate. Adjusting the guide plates covers up certain nozzles, thus controlling the flow of air on the packages.

Heat shrink wrap product packaging oven or tunnel apparatus and processing methods are provided which incorporate or utilize airfoils in conjunction with hot air-providing side walls to desirably control impact of hot air onto a product wrapped with a tube of heat shrink wrap film and being conveyed on a conveyor thereby. In such heat shrink wrap product packaging apparatus and methods, such airfoils can be movable, e.g., rotatably moveable, relative to the side walls to vertically alter an air impact point onto the product.

This invention provides a film wrapped pack of containers that allows a container to be removed while maintaining the remaining containers together. This can be accomplished by providing a sleeve wrapped pack of containers with two perforated lines registered on the top of the film before film wrapping. By peeling off the top part of the perforated film, the containers are exposed, allowing for the removal of a container while maintaining the integrity of the film

An apparatus for shrinking a shrink film onto a package formation includes a shrink tunnel-system having gas conductors that direct hot gas into the tunnel's interior along first and second flow-directions that are opposite to each other and parallel to a direction in which the package formation is conveyed through the shrink tunnel.

Disclosed is a packaging device for packaging products, during which the products are conveyed along a conveying direction in order to be packaged. The batches include at least two products, arranged transversely to the conveying direction. The device includes a feeder for receiving products travelling in single file through an upstream pick-up area and conveying same to a set-down area for later packaging. The feeder includes: in the pick-up area, a transfer unit transferring products arriving in single file to the unit; and a position-controlled movable collector receiving and then moving at least one product in a controlled manner from the transfer unit to the set-down area. The device also includes a conveyor in the set-down area, on which the at least one collector deposits the at least one product that it collected from the pick-up area. Also disclosed is a machine using the device and to a corresponding method.

A system and method for using waste heat from computing devices is disclosed. Computing devices may be positioned in a device rack and output exhaust air such that heat is transferred into a heat chamber with controllable temperature and a work item rack that is configured to hold one or more work items. By transferring the heat from the computing devices to heat or preheat the heat chamber, the captured heat can be used for useful work such as dehydrating, baking, drying or curing. Humidity can also be controlled, and conveyors may be used to improve the flow of work items. The energy reused may be calculated, recorded and attributed to the work items processed or the work performed by the computing devices.

An airflow orifice adjusting device of a package thermal-shrinking oven includes at least one airflow orifice board mounted to an inside surface of a hot airflow box of the package thermal-shrinking oven and formed with series of airflow orifices, at least one track board mounted to an outside of the hot airflow box and formed with a plurality of track holes, a plurality of adjusting levers, and a plurality of airflow-blocking adjusting plates mounted to the airflow orifice board and each formed with a plurality of adjusting orifices. Each of the airflow orifices of the airflow orifice board discharges a hot airflow. The adjusting levers each have two ends that are respectively formed as a connecting portion and an operating portion. The connecting portion extends through the track holes of the track board to connect to one end of the airflow-blocking adjusting plate, so that a leftward or rightward horizontal moving operation of the operating portion of the adjusting levers causes the airflow-blocking adjusting plate to correspondingly perform a reversely directed horizontal movement in a rightward or leftward direction. The adjusting orifices of the airflow-blocking adjusting plates respectively correspond to the airflow orifices of the airflow orifice board, so that each of the adjusting orifices may completely or partially match with or completely un-match with a corresponding one of the airflow orifices of the airflow orifice board to adjust a discharging flowrate of the hot airflow and discharging of the hot airflow or not.

An apparatus comprises a shrink tunnel for use in a production system for the production of packaging units from packaging materials filled with a product and having shrink film shrunk thereon, the shrink tunnel comprising a tunnel zone, heating means for application of heat to shrink the shrink film onto packaging units moved through the tunnel zone, the tunnel zone being maintained at a tunnel temperature equal to a target operating temperature, wherein the tunnel has an operating mode and a standby mode, wherein heat output during the standby mode is less than heat output during the operating mode, and wherein the standby mode is triggered by at least one of a time control and a signal control.

A system for packaging a food product including a conveying system for supporting and moving the food product. The system includes a detection device for collecting data related to the shape of the food product while the food product is supported by the conveying system. The system also includes a film dispensing device for dispensing one of a plurality of different films. A controller configured to direct the film dispensing device to select one of the plurality of films for dispensing. The system also includes a wrapping device for wrapping the food product in the selected film.
