The present invention provides a central shaft mechanism, which is arranged on the base of a winding machine, including a central shaft component, a central shaft is arranged in the central part of the central shaft component, the central shaft component is also provided with a bearing support structure and a plurality of first limiting structures, and the central shaft component is fixed and limited in the base of the winding machine through the first limiting structures. The central shaft mechanism of the present invention has stable position, stable and reliable operation, and can reduce the working noise and noise during operation. In addition, it can be packed separately from the base during transportation, and can be quickly installed on site, which can not only provide more stable support, but also reduce the height of the turntable of the height winding machine.

A product packaging system comprises a plurality of product sources (2, 4, 6) delivering product to a final collating and packaging line (10). The output from each machine is delivered by separate conveying means (8) delivering the products directly into a collating conveyor (20) which in turn delivers the collated products to a packaging line. The collating conveyor comprising an endless conveyor carrying a plurality of compartments, each compartment receiving from said conveying means products to be packaged. The compartments are configured to enable their sizes to be changed, and the endless conveyor comprises a track arranged in a vertical loop and a plurality of product supporting members mounted for movement along the track, each supporting member being driven along the track and controllable independently of the other supporting members.

Method for filling and closing a package including the operations of introducing two arms through the mouth, each one having or bearing a gripping tool and impressing a mutual distancing movement on the arms to expand the package with a retention mechanism which operates outside the package to grasp the walls of the package arranged between the arms and the retention mechanism while the retention mechanism approaches and fits over the gripping tool of each arm, such that when the arms move in the direction of the mouth of the package, the arms carry the grasped walls of the package to produce folds towards the interior of the package. For flexible tubular net packages, the at least one gripping tool on each arm has the shape of a protuberance and that the method includes passing through a wall of the package with the gripping tool

A thermoform packaging machine comprising a forming station for producing troughs in a bottom film, a sealing station for sealing troughs that contain a product, and at least one cutting station arranged on a machine frame. The thermoform packaging machine may include at least two clamp chains for holding and conveying the bottom film in a production direction through the packaging machine. The clamp chains may be guided by chain guides that extend at least from the forming station along an infeed line to the sealing station. Each chain guide may include an upper guide surface and a lower guide surface between which a respective one of the clamp chains is guided. In one embodiment, the chain guides are oriented horizontally at and along both the forming station and the sealing station and the chain guide ascends from the forming station to the sealing station along the infeed line.

A sealing machine having a movable carriage assembly which utilizes a counterbalance and two servo motors is disclosed. The counterbalance allows high throughput operation without excessive mechanical vibration. The use of two servo motors allows independent control of the horizontal movement of the movable carriage assembly and the vertical movement of the jaws. The use of two servo motors also allows adaptation to articles or packages of various dimensions. In some embodiments, an optical sensor is used to detect the position of the package to be sealed, and the movement of the movable carriage assembly and the jaw is altered based on the detected position.
