A machine for providing cushioning products of varying lengths from a supply of a web material having sequential transverse rows of inflated protrusions. A pair of opposing feed members form a feed nip for moving the web along a path of travel. At least one sensor detects location information for the sequential rows of inflated protrusions as the web travels along the path of travel. A severing device is moveable between (i) an engaged position to separate the web transversely or perforate the web transversely and (ii) a disengaged position. A controller is programmed (i) to receive the location information and (ii) to operatively control the severing device to move it to the engaged position when a selected row is in a determined position relative the severing device.

An incision station for making a plurality of weaknesses respectively on a plurality of portions of a web, for producing a plurality of packages each of which including a supporting sheet corresponding to a respective portion of the portions and an opening system corresponding to the weakness made on the respective portion. The station includes a plurality of motor driven incision bodies for making incisions in the respective portion to create the weaknesses. The incision bodies are also controlled to obtain a distance needed to contact the respective portion. This invention also relates to a packaging machine which includes the incision station and a incision method for making the above-mentioned plurality of weaknesses.

An object of the present disclosure is to prevent wrinkles in a folding line portion of a paper irrespective of the conditions such as the type, the size, and the like of the paper, thereby securing the precision of the position of a folding line when a flap (such as a flap portion) of an envelope is folded back. The folding unit comprises a pair of an upper and a lower guide plates that defines part of the paper conveyance path at the folding position, and the folding plate is configured so that, when turning from the placement position to the overlap position, a lower face of the folding plate overlaps an upper face of the upper guide plate of the pair of the upper and the lower guide plates.

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.

A defect detecting device includes a detection unit and a movement mechanism. The detection unit includes a support, an arm supported by the support swingably around a swing shaft, and a sensor for detecting a displacement of the arm relative to the support. The arm includes contactors. The movement mechanism keeps the contactors away from a feed plane during a feed phase of a sheet panel, and moves the contactors to the feed plane and then moves the contactors from the feed plane during a pause phase of the sheet panel. The defect detecting device further includes a determination part configured to determine whether a defect in bag making is present based on data from the sensor.

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.

Automated bag forming systems and methods for their use are disclosed. The automated bag forming systems described herein can be configured to receive a web of bag material and produce individual bags through a sealing and cutting process possessing a high degree of speed, precision, and reproducibility.

Provided are an electrolytic cathode structure that can suppress the degradation of an activated cathode even if a reverse current flows upon the stoppage of operation of an electrolyzer in an electrode structure allowing the distance between the electrode and an electrode current collector to be maintained at an approximately constant value, and an electrolyzer using the same. The electrolytic cathode structure includes a metal elastic cushion member 1 compressed and accommodated between an activated cathode 2 and a cathode current collector 3. At least a surface layer of the cathode current collector 3 consumes a larger oxidation current per unit area than the activated cathode. The electrolyzer is partitioned by an ion exchange membrane into an anode chamber for accommodating an anode and a cathode chamber for accommodating a cathode. The electrolytic cathode structure is used for the cathode.

A machine for assembling a container accommodating perishable good comprises bag placing means configured for inserting a bag into a frame and everting a bag rim portion over the frame and bag securing means. The bag securing means further comprises: an internal member having a perimeter conformable with a cross section of the bag thereat the internal member insertable into a main portion of the bag; and at least one external member conformably pressing the rim portion everted over the frame to the main portion. The internal and external members are provided with cooperatively disposed effectors configured to secure the rim portion and the main portion together when the rim and main portions are pressed to each other.
