, ApplicationCross-section: rectangular or round with centered sealTypes of seal: lap seal, distant seal and turned fin sealBags with a flat bag width of less than 60 mm are called stickpacks. The flat film is formed into a tube with the seal concealed completely within the forming shoulder.We also develop stickpack forming shoulders for paper for your special needs.We are not limited to a minimum flat bag width. The smallest forming shoulder we have ever manufactured was for a flat bag width of 6 mm. Our entire stickpack forming shoulders are milled and thus ideal for multilane purposes. Each forming shoulder of a series is identical to any other.Forming shoulders with a flat bag width exceeding 60 mm are usually called universal forming shoulders. They are made of sheet metal and their application in multilane machines is limited.Benefitsreliable forming processreduced forming height and improved stability compared to a forming process that does not utilize forming shouldersimproved stability of film run compared to a process that utilizes heads of forming shouldersno special qualification required for installation and operation of the forming shoulderideal for the application in multilane stickpack machinesLimitationscostly manufacturing and testing processesfrequent adoption to new film material and process conditions necessary Find information on how to open stickpack forming shoulders easily using the “easy-to-open” mechanism

They are also known as folding boxes or flowpack forming shoulders.Our forming shoulders are suited especially for use in high-speed flowpack packaging machines.Benefits wrinkle-free formingminimum installation effortLimitsDue to the infeed of the film from top the piece goods have to be pushed within the forming shoulder. Thus the design of the forming shoulder depends on the geometry of the conveyor and the pitch point of the driving pin.Get more information about why forming shoulders are applied to horizontal bag making machines

, Applicationfilling pipe: round or rectangulartypes of seal: centered lap seal or centered distant or turned down fin sealA forming head is not a finished forming shoulder but the first step in the forming process that forms the film into a flat tube. The second step then moulds and calibrates the tube into its final form. The required parts have to be manufactured and integrated into the machine by the customer himself.The forming parts have to be adjusted precisely to the forming head . We supply a sketch to show where the forming parts should be situated. Finally it depends on the customer where the forming parts are positioned.Especially low-priced we offer a series of standardized forming heads suitable for bags with a flat bag width from 13 mm to 42 mm.

, Applicationcross-section of filling tube: roundform of the seal: centered lap and turned-down fin seal, right side over left sideUniversal forming shoulders are efficiently manufactured forming shoulders for bags with a flat bag width between 50 mm and 250 mm. Two different series are offered in our brochure “universal forming shoulder”. Besides price information the brochure gives the dimensions of each forming shoulder. Due to the pre-defined dimensions of the forming shoulder the design process of the machine can be faster.Series ffcompactForming shoulder series ffcompact is developed for machines which offer only a little installation space. The infeed angle is rather small and causes more stress on the film material compared to a forming shoulder with a higher infeed angle. We suggest applying resilient film materials like mono-plastic films on these forming shoulders.Series ffcomfortThis forming shoulder series offers an infeed angle of 45°. It is therefore also suitable for more sensitive laminated films. Due to the constant infeed angle we offer the option “infeed rolls” for this series. Infeed rolls align the film run to the surface of the forming shoulder in the most suitable way. By choosing this option two infeed rolls are attached to the infeed of the forming shoulder.Benefitsreasonably pricedBoth lap seal and fin seal may be produced with one forming shouldersimply obtain spare parts due to standardized dimensionsseries ffcompact: small height of the forming shoulderLimitsapplicable film materials: only mono-plastic and laminated-plastic film without layers of paper.Obtain the brochure of the universal forming shoulders

, ApplicationThe longitudinal corrugator was invented as a device for the corrugation of paper. It is the basis for the production of longitudinal corrugated cardboard or cross-corrugated cardboard. It is conceivable that not only paper but also plastic, woven and non-woven fabric or tin foils can be applied as raw material.The longitudinal corrugator is one of our products. We design and manufacture the longitudinal corrugator exactly for your application.CharacteristicsThe film material is formed by the longitudinal corrugator. The forming process is similar to that of an extruder. Theoretically the corrugated profiles can be produced with an endless length. The geometry of the profiles to be formed can be designed nearly without restrictions.The longitudinal corrugator is effectively applicable to the production of cross-corrugated cardboard or honey-comb cardboard. Even applications beyond the processing of paper were realized.BenefitsOptimum film run and re-production is possible due to an exact calculated Design.Longitudinal corrugator manufactured in best quality due to in-house manufacturing.LimitsOptimal for the processing of continuous product streams.Up to now each longitudinal corrugator has a fixed format.Read more about the longitudinal corrugating technology

, Applicationform of seal: distant fin seal on the edge of the baginfeed of film: from bottomThe horizontal machine concept is used if the goods are fragile or heavy or the order of a stack has to be kept.Three-side sealed bags are suitable especially for aseptic packaging. There are no leaps of the layers in the seals. Therefore the bags are impermeable. The inverse horizontal forming shoulder for three-side sealed bags forms the longitudinal fin seal to the edge of the bag.
