A spring feeding device configured to feed a spring (9) comprises a feeding member (60) delimiting a channel (68), a pusher (70) configured to push the spring (9) along the channel (68) delimited by the feeding member (60), and a drive mechanism con-figured to displace both the feeding member (60) and the pusher (70) such that the feeding member (60) and the pusher (70) move in opposite directions (91, 92).

A support shaft capable of supporting a wound body with a long sheet wound therearound includes a first projection located at a proximal end of an outer peripheral part, and a second projection located at a distal end of the outer peripheral part. A core body of the wound body includes a one-end-side first recess part located at one end of an inner peripheral part, an other-end-side firsts recess part located at an other end of the inner peripheral part, and a second recess part located to extend from the one end to the other end. In a state where the core body is mounted on an outer periphery of the support shaft, the first projection engages the one-end-side first recess part or the other-end-side first recess part. When the core body is mounted to the outer periphery of the support shaft, the second projection engages the second recess to allow the circumferential position of the first projection to be aligned with the circumferential position of the one-end-side first recess part or the other-end-side first recess part around a central axis.

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 packaging apparatus (e.g., otherwise described as a mailer apparatus with a material feeder assembly, a product supply assembly, a folding assembly, a sealing assembly, and/or a packaging apparatus system (e.g., including a controller thereof) for controlling the operation of the packaging apparatus. The packaging apparatus is configured for delivering products and material at the same time, and forming a package (e.g., a mailer, or other package) directly around the products. A material feeder assembly of the packaging apparatus supplies material for packaging and a folding assembly receives the plurality of products and folds the material around the products. The sealing assembly seals the material around the at least one product to form packages (e.g., makes a longitudinal seam, forms a transverse seam, and/or separates the material at the transverse seam).

A first film can be conveyed through a horizontal form-fill-seal machine that contains tooling stations in which bottom sealer bars are positioned in different tooling stations relative to side sealer bars. The first film can be processed by the machine to form a first pouch. After the first pouch is formed, a vertical height of one or more of the side sealer bars and/or one or more of the bottom sealer bars can be selectively adjusted. The same bottom and side sealer bars remain in the machine during the selective adjusting of the vertical height. After the selective adjusting of the vertical height of the component, a second film can be conveyed through the horizontal form-fill-seal machine. The second film can be processed by the machine to form a second pouch having at least one dimension that is different than the first pouch.

Method, machine and installation for vacuum packaging of products, where a plurality of individual bags closed at one end and open at the opposite end with at least one product therein are generated. For generating the bags, a transverse cut and a complete transverse seal on both sides of the transverse cut are made on the film tube, and a transverse cut without complete transverse seals on the sides thereof is made at a distance (L) substantially equal to the desired length of the bag to be generated from the transverse cut and seal on both sides. Each bag is oriented at 180 degrees with respect to the bag previously generated in the forward movement direction.

The disclosure relates to a sheet, a pouch containing pills made of a sheet material and a web of multiple of said pouches. The disclosure also relates to a method for manufacturing said web which makes use of said sheet. The pouches allow for optimal visibility of information printed on the pouches as well as optimal visibility of the pills for inspection purposes.

A medicine packaging apparatus 10 has a packaging paper supplying part 42; a sealing device 50 for forming a packaging bag; a medicine introducing part 80 for introducing the medicines M from an opening portion of the packaging bag P in an unsealed-state; a detecting part 90 for detecting presence of the medicines M in an introducing path for the medicines M by the medicine introducing part 80 and a determining part which can determine that a packaging failure occurs under a condition that the presence of the medicines M is detected by the detecting part 90 within a time period after a timing of starting to seal the packaging bag P in which the medicines M have been introduced and before a timing of introducing the medicines M to be packaged in a subsequent packaging bag P through the medicine introducing part 80.

Described is a compensating device applicable on intermittent advancement packaging machines with wrapping material constituted by a film made of a flexible plastic material, for continuous compensating of a stretching of the film during drawing thereof, the machine comprising a first drawing group of the film, a mobile element able to exert a determined force on the film during advancement, the mobile element being conventionally known as a dancer and a second drawing group of the film arranged downstream of the first drawing group, where each drawing group is provided with a sensor for detecting markers located at regular intervals along the film, the compensating device being constituted by a third drawing group, located between the first and second drawing groups, the third drawing group being provided with a marker sensor, the third drawing group being provided with independent motorisation and an automatic roller opening system.
