A machine for producing bags includes a station for forming a tube, which forms a band of transversely perforated flexible material into a tube, a holding station for retaining the tube, a folding station for forming a bottom at the end of the tube, a folding roller having a folding blade for folding a flap at the end of the tube and a tear-off bar for pinching the tube against the drum, the folding station and the holding station being configured to jointly exert a traction on the tube and detach a portion of the tube. The tear-off bar is disposed behind the folding blade, the machine controlling the rotation of the folding station to synchronize the drum with the front of the tube.

A method of packaging a series of differently shaped objects. The method includes receiving a first object to be packaged and identifying a first length of a stock packaging material suitable for enclosing the first object. The method continues by creating, with a bag making machine, a first bag from the stock packaging material having approximately the first length, which leads to substantially enclosing the first object in the first bag. Then the method continues by receiving a second object to be packaged, the second object having a shape or size different from the first object. A second length of the stock packaging material suitable for enclosing the second object is identified. The method continues by creating, with the bag making machine, a second bag from the stock packaging material having approximately the second length, followed by substantially enclosing the second object in the second bag.

A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.

Apparatus and method of manufacturing open-mouth bags (2), comprising a storage device (3) with a supply (4) of bag film (5), a control device (60) for controlling, a conveying device (6) for conveying the bag film (5) and/or the bag body (16) along a conveying path (7), a welding device (8) with welding means (9, 10) for making a bottom seam (11) in the bag film and a cutting device (12) with a cutting means (13, 14) for separating a predetermined film length (15) of the bag film (5) to form the bag body (16) of an open-mouth bag (2). The control device (60) controls the conveying device (6) so as to cause a relative motion of the bag body (16) and the bag film (5) and a distance (37) between the bag body (16) and the bag film (5) is generated prior to making the bottom seam (11). The control device (60) controls the conveying device (6) and the welding means (9, 10) so that while welding the bottom seam (11) the welding means (9, 10) extend at least up to the bottom end (23) of the bag body (16).

A method and machine for visual inspection of bags for quality control, in particular providing a way to inspect pinch bottom bags and flat bottom bags continuously exiting a production line, without the need to stop or delay the production or movement of the bags.

The invention relates to a system for manufacturing medical pouches and a method for manufacturing medical pouches in a system, said pouch being made from two layers of plastic film and at least one component per pouch, the system comprising a group of positioning aids for the components as well as a group of supports for the positioning aids, the positioning aids being supported on the supports which are conveyed in an endless path with the aid of a guiding mechanism, the system further comprising a component application station designed to bring a component, which has been introduced into the station by a positioning aid with the aid of a support, into a joining connection with the plastic film. The invention is characterized in that on the endless path, the supports are alternately guided first along a process run and then along a return run; the supports are placed at a certain distance from one another in the process run, are accelerated to increase the distance therebetween when the supports travel along the return run, and are decelerated to reduce the distance therebetween again when the supports intermittently travel along the process run. As a result, the system requires fewer product-specific parts.

Systems and methods for communicating cutting instructions for cutting a protective cover for a personal device, and for validating protective cover materials prior to cutting the protective cover in order to prevent unauthorized and/or improper use of the protective cover materials. Systems and methods for cutting a protective cover for a personal device after validating protective cover materials and receiving cutting instructions based on a user-selected personal device for which a protective cover is desired.

A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.

According to an apparatus for successively making the plastic bags, wherein the wastes 14 are formed in at least two areas adjacent to each other widthwise of the plastic film 1, and the apparatus can determine whether all of wastes 14 of each of the areas are discharged.

The apparatus comprises at least one partition plate 20 in a suction path 16. The suction path 16 is divided into at least two widthwise of the plastic film 1. The wastes 14 is guided to each of the divided paths 21A, 21B, 21C, 21D and is discharged. The wastes 14 is detected by an optical sensor when the wastes 14 is discharged to each of the divided paths.

The present invention relates to a flexible package-forming machine for horizontal packaging and method of manufacturing flexible packages. The proposed forming machine consists of an unwinding unit (11), a perforating unit (12), a folding unit (14), a welding unit (16), and a cutting unit (17), wherein a compensating unit (13) is further included intercalated between the perforating unit (12) and the folding unit (14), linking a section with intermittent forward movement (S1) of the flexible band (1) where the flexible band moves in an intermittent manner and including the perforating unit, and a section with continuous forward movement (S2) where the flexible band moves in a continuous manner and including the folding unit, flexible band being accumulated in said compensating unit during the forward movement of the section with intermittent forward movement (S1) and the accumulation being reduced during breaks in the forward movement of the section with intermittent forward movement.
