A method for controlling the operating parameters of a sealing unit of the follower type in a product packing machine, wherein the sealing unit comprises a sealing module movable with reciprocating motion along a feed path of a tubular film to be sealed. The method is implemented in accordance with a plurality of operating parameters and comprises the step of setting the value of at least one input operating parameter selectable at least between sealing time and production speed. The method also comprises the step of calculating the values of the remaining, unselected operating parameters as a function of the set value, where one or more of the remaining operating parameters are subject to restrictions connected with the machine architecture. The method also comprises the step of checking that the values calculated are compatible with respective reference ranges and/or with the restrictions.

One or several protrusions (314a, 314b) of said magnetic field concentrator (306) cooperate with one or several indentations or openings (312a, 312b) in said main body (302) such that said magnetic field concentrator (306) and said main body (302) is securely bonded together.

A head for a horizontal flow wrapper packaging machine for forming a bandolier of product packages. The head includes a rotatable first shaft having a plurality of knife elements each including a blade and first and second upper crimping elements. The head also includes a rotatable second shaft having a plurality of anvil elements. A rotation speed of the second shaft is independent of the rotation speed of the first shaft. Each anvil element includes perforation and cutting surfaces and first and second lower crimping elements. A rotation speed of either the first shaft or second shaft is changed to move either a knife element or an anvil element, respectively, between a perforation position and a cutting position. The first upper and first lower crimping elements and the second upper and second lower crimping elements also mate to crimp the packaging material in either the perforating or cutting positions.

The disclosure relates to a filling machine (1) for filling a package (2) of a web of packaging material with a food product. The filling machine (1) comprises a jaw system (3) adapted to seal the package (2) after being filled with the food product. The jaw system (3) is equipped with means (4) for providing a unique mark (5) on the package (2). The filling machine (1) further comprises a sensor (7) arranged downstream of the jaw system (3) which is adapted to detect the mark (5) on the package (2), and a cutting knife (8) adapted to cut the package (2) from the web of packaging material. The cutting knife (8) is movably arranged in the filling machine (1), such that the cutting knife (8) can be adjusted in relation to the package (2) based on the detected mark (5) before cutting the package (2) from the web of packaging material. The disclosure also relates to a method for filling a package (2) of a web of packaging material with a food product.

A production method of a sealed single-dose break-open package; wherein the package comprises: a first sheet of semi-rigid plastic; a second sheet of flexible plastic superposed on and sealed to the first sheet to define a sealed pocket that contains a dose of a product; and a weakened zone made in a central zone of the first sheet for guiding, after bending of the package, controlled breaking of the first sheet at the weakened zone to cause formation of an outlet opening for the product through the first sheet; the method includes making in a surface (8, 10) of the first sheet an incision that constitutes the weakened zone; wherein the incision is made through plastic deformation of the material using an incision tool having a tip that is not sharp, that is, that has a round shape for deforming rather than cutting.

A form-fill-seal machine forms a bag by filling and sealing a packing object in a wrapping material. The form-fill-seal machine includes a thickness adjustment unit which adjusts a thickness of the bag and a control unit which controls an operation of the thickness adjustment unit. The control unit acquires thickness information obtained in a rear stage of the form-fill-seal machine and relating to a thickness of the bag and controls the operation of the thickness adjustment unit on the basis of a result obtained by performing statistical processing on the thickness information.

A control apparatus for controlling a packaging machine that includes a conveyance mechanism for conveying an item to be packaged includes: an acquirer configured to acquire a detection result from a sensor for detecting an item to be packaged; a determiner configured to obtain elapsed time from a predetermined time point until when the item to be packaged is detected by the sensor, based on the detection result acquired by the acquirer, and determine a shift direction in which the item to be packaged is shifted from a predetermined position, based on the elapsed time; and a controller configured to control, for the item to be packaged for which detection is performed by the sensor, implementation of any one of downstream units that are downstream of a unit in which the detection is performed by the sensor, based on the shift direction that is determined by the determiner.

A fill-packaging method for plural rows, a fill-packaging machine for plural rows and a fill-packaged body include a wide-width cylindrical body forming process for continuously longitudinal-sealing a plastic film longitudinally unreeled in the longitudinal direction to continuously form a single wide-width cylindrical body, a sealing and cutting process for continuously heat-sealing one or more widthwise positions of the wide-width cylindrical body to form longitudinally border sealed portions and continuously cutting the longitudinally border sealed portions in the longitudinal direction to cut out the wide-width cylindrical body into a plurality of narrow-width cylindrical body rows independently arranged in parallel, and a bag-making process for continuously manufacturing packaged bodies by applying horizontal sealing to each of the narrow-width cylindrical body rows separated and run independently in the longitudinal direction at predetermined intervals while filling a packing material therein.

A bag-making and packaging apparatus creates one product per cycle by packaging articles in a bag made from a film. The bag-making and packaging apparatus includes a longitudinal sealing mechanism, a guide, an article sensor, a transverse sealing mechanism, a cutting mechanism, and a prediction unit. The guide guides the articles which fall from above into a film tube. The transverse sealing mechanism forms a transversely sealed part in the film tube with each cycle. The cutting mechanism cuts the film tube in the transversely sealed part with each cycle. The prediction unit predicts whether or not jamming of the articles could occur in the transverse sealing mechanism on the basis of an output of the article sensor with each cycle. When the prediction unit has predicted that the jamming could occur in a certain cycle, the cutting mechanism does not cut the film tube in the certain cycle.

A bag making and packaging machine has pull-down belt mechanisms, a transverse sealing mechanism, a rotatable folding member, and a gas blowing mechanism. The folding member, before the transverse sealing mechanism, seals a cylindrical film, pushes against a side portion of the cylindrical film to thereby fold the cylindrical film inward and form a fold in the cylindrical film. The gas blowing mechanism blows a gas onto the fold to thereby inhibit the cylindrical film from sticking to the rotating folding member.
