摘要:
The invention relates to a packaging machine (1). According to the invention, the film (11) is transported from a roll to a forming station (2), whereupon it is heated and deep drawn by a forming tool (9) to form a packaging tray. The forming tool can also contain a cutting device enabling the packaging trays (10) to be cut of the strip of film (11). The rest of the strip of film (11) is wound by means of a coil (13). The packaging trays thus produced are transported by means of the conveyor belt (14) to the filling station (4) and filled with packaging items. The filled packaging trays are then closed with a covering film (12) in an evacuation and sealing station, said covering film being used to seal the packaging trays (10). A cutting system is integrated into the sealing tool (15) and is used to cut the finished packaging from out of the covering film (12). The remaining covering film is wound by means of a coil (16). The finished packaging is removed by means of an exit strip (17).

A buttonhole sewing machine comprises a needle thread feeding mechanism, in which the needle thread is guided over a cam disk, which performs a rotation during two stitches of the needle. Along its periphery, the cam disk has such a curvature that tensioning and releasing the needle thread complies with the requirements of alternately sewing a single thread chain stitch and a double thread chain stitch during the sewing of a zigzag buttonhole seam.

An adjustable table assembly comprising a planar work surface which is pivotally secured at the rear edge thereof to a pair of parallel, laterally spaced, vertical support members such that the work surface can be moved substantially continuously between a fully horizontal, extended position and a fully vertical, retracted position. Unique brackets attach the rear ends of upper and lower linkage bars to the support members with the brackets and support members being configured for cooperative, mating engagement whereby the brackets are adjustably longitudinally slidable upon the support members. The forward brackets attaching the forward ends of the lower linkage bars to the upper linkage bars are also configured for adjustable, longitudinal sliding engagement therewith.

In order to be able to produce packages economically and when the package design results in undercuts being provided in a deep-drawing tool for its manufacture, a simple and practical solution for the movement of the lower parts in each of the required work stations is advantageous. These lower parts are generally vertically movable in order to be able to easily open the mold. An inclined opening of the mold or rather removal of the lower part is achieved according to the invention in such a manner that between the lower part of the tool and the lifting device for facilitating its vertical movement there is provided a carriage guide which enables also an easy horizontal movement. A guide pin fastened on the carriage guide is part of a guide system which controls a desired forced inclined guided opening of the mold. The guide system can be used in deep-drawing tools, sealing tools and similar ones.

摘要:
A design-time status schema model describes the progress of a data object through a computing process. The status schema model includes status variables, processing actions and constraints for performing actions. The status schema model also may describe permitted changes to a status variable in response to performing an action. At runtime, the status schema model is used to control processing performed by, or on, an instance of a data object corresponding to the status schema model.
摘要:
The invention relates to a packaging machine for packing food products in a plastic packaging, said machine comprising a device for applying a transponder to the plastic packaging, and a system for data exchange between the transponder and a computer unit and/or a regulating unit, by which means data can be transmitted to the transponder or called therefrom.
摘要:
The present invention relates to a packaging machine with a forming station, which forms depressions in a sheet of film, wherein a heating element heats the sheet of film before the deforming, in which the heating element has a multiplicity of discrete heating means which can be activated individually or in groups, and so the sheet of film has temperature gradients.
摘要:
The present invention relates to a film, further comprising a radiation-curing coating, wherein the coating comprises a polyurethane polymer which contains (meth)acrylate groups and which is obtainable from the reaction of a reaction mixture comprising (a) polyisocyanates and (b1) compounds which comprise (meth)acrylate groups and are reactive towards isocyanates and wherein the coating further comprises inorganic nanoparticles with an average particle size of ≧1 nm to ≦200 nm. It also relates to a process for the production of such coated films, the use of such films for the production of shaped articles, a process for the production of shaped articles with a radiation-cured coating and shaped articles which can be produced by this process.
