Abstract: A machine for packaging soft products, including a conveyor defining a ring-shaped path having an active linear lower branch facing a feed plane and a non-active linear upper branch Each of a plurality of carriages supports a tooth, projecting towards the feed plane during the passage on the lower branch. A transfer device moves one group of products at a time, with a corresponding sheet of wrapping material folded around the group, towards the feed plane and to a receiving compartment defined by a first and a second tooth, along a second direction transversal to a first direction. Along the lower linear branch there are a number of teeth equal to the number of groups positioned or arrived on the feed plane. Each tooth is configured to define simultaneously a pushing tooth and a tooth containment when the tooth is interposed between two groups along the feed plane.

Abstract: A machine for packaging soft products, including a conveyor defining a ring-shaped path having an active linear lower branch facing a feed plane and a non-active linear upper branch. Each of a plurality of carriages supports a tooth, projecting towards the feed plane during the passage on the lower branch, and configured for retaining and feeding along the feed plane the groups of products. A transfer device moves one group of products at a time, with a corresponding sheet of wrapping material folded into a “U” shape around the group, towards the feed plane and to a receiving compartment defined by a first and a second tooth, along a second direction transversal to a first direction. Each tooth includes a head permanently connected to the carriage and an operating portion in contact with the groups which can be separated from and reconnected to the head.

Abstract: The device for sorting items, such as rolls, is provided downstream of a first number (N) of feeding channels (Ca) of items (R), which feeding channels (Ca) are provided with dispensing members (S) for a controlled release of the items (R). The device (100) includes: a number of mobile tracks (5) equal to the first number (N), arranged downstream of the (N) feeding channels (Ca) and operatively associated in pairs, so as to define operating gaps (H1) between successive pairs. The first mobile tracks (5) are movable in reciprocal synchronism, transversally (W) to the feeding channels (Ca). A second number (M) of second mobile tracks (6) are arranged downstream of the feeding channels (Ca) and are disposed each one between successive pairs of the first tracks (5) at the operating gaps (H1).

Abstract: An apparatus for wrapping groups of rolls of products with a sheet of film comprises a station for packaging and moving, with a stepping motion, in a predetermined direction, a succession of groups of products wrapped in a sheet of film, having an open front side defined by two opposite flaps, and means for closing the open side comprising a unit consisting of: two pairs of mobile elements, arranged side by side in said direction, to allow the flaps of film of the two groups of products arranged one after another to be brought together and closed; first movement means for the unit, allowing synchronized movement of the two pairs of elements, respectively, in the same direction as the groups, for one group feed step, bringing together and closing the flaps, and a movement opposite to said direction over a distance equal to the distance previously traveled, simultaneously with a feed step of the groups to be packaged, so as to position the unit at two further and subsequent groups of products to be closed.

Abstract: In a machine for the production of packs of rolls of paper, comprising a supporting surface designed to lift the rolls of paper, arranged in two or more rows, towards a zone in which there is a sheet of plastic film, in particular polyethylene, to be wrapped around the rolls to form the pack, the sheet is closed on the lower side of the pack by initiating a process for activating sheet horizontal flat folders, suitably combined with the return stroke of the two parts of which the supporting surface consists. The process allows correct closing of the two flaps of plastic film on the lower side of the pack, guaranteeing the stability of the configuration of the various rows of rolls.

Abstract: An apparatus for perforating a packaging film comprises at least one rotary cutter, which is rotationally driven by suitable drive means, and a fixed cutter, the cutters having respective blades by which a packaging film moving between the knives themselves on a supporting surface is perforated at regular intervals. The rotary knife is rotated by drive means which move it at a controlled speed of rotation that varies within one full angular revolution.

Abstract: An apparatus for automatically controlling the work flow of a machine—equipped with effectors (2) driven by rotational motors (12)—comprises: electronic storage means (11) having resident functions that relate the angle of rotation described by a controlling motor (12) with the desired instantaneous position of a controlled effector (2); means (13) for detecting the actual instantaneous position of the controlled effector (2); comparator means (14) for determining the positional error of the controlled effector (2) relative to a given expected position upon reaching a certain angle of rotation of the controlling motor (12); and means (15a) for controlling the motor (12) of the controlled effector (2), which receive the error signal from the comparator means (14) and apply to the motor (12) a corresponding corrective action designed to control and synchronize the angular position of the controlled motor (12) with that of the controlling motor (12).

Abstract: A method for stopping and restarting an automatic machine (1) for wrapping products (2), in particular rolls of toilet or kitchen paper, in a collective pack (3) using a packaging film (4a) unwound from a first reel (31a). The method comprises the following automatic sequence of steps: reducing the speed of the machine (1); and stopping the feeding of the products (2) and of the film (4a) at suitably synchronized intervals from each other relative to the processing of the products (2). The method subsequently comprising the steps of: substituting the first reel (31a) of the film (4a) with a second reel (31b); loading the film (4b) on the second reel into feed means (33, 10 34). Restarting the machine (1) at reduced speed and thereby automatically activating the following sequence of steps: unwinding and positionally centering the film (4b); and restarting the feeding of the products (2) and of the film (4a) at suitably synchronized intervals from each other relative to the products.

Abstract: A method for the production of packs of rolls of paper, in which the rolls are collectively wrapped with a sheet of plastic film which is folded and sealed, allows a rational method of closing one front surface of packs and the simultaneous automatic production of an opening at the surface for the pack handle. An apparatus for implementing the method comprises suction plates, which move vertically in opposite directions to join end flaps of the sheet of plastic film, closing the pack. The flaps are joined with the aid of means designed to neatly arrange the material of the side surface of the sheet between the flaps inside the flaps as they are joined. Further means seal the two flaps and make a pack handle opening.

Abstract: An automatic packaging machine for packaging products into packs comprises: a wrapper forming line along which there is a succession of at least three operating stations positioned above a sliding surface along which the products are fed with a stepping motion by mobile pusher elements. The forming line co-operates with a lift located below the product sliding surface and vertically and alternately mobile between a lowered level, at which it receives products on its loading table, and a raised level, at which it places the products on the sliding surface of the forming line, feeding them between the pusher elements with a sheet of wrapping material laid on top of the products. The machine comprises adjustment means for a product feed line, the wrapper forming line, the operating stations and the pusher elements.
