A roll of separable bags which leaves no scrap material and method of making a roll of separable bags which leaves no scrap material is disclosed herein. An elongated tube of material having a length and a width is laid flat, forming a web of material. The web of material comprises an outer and an inner sheet portion. First and second seals are formed widthwise across the outer and inner sheet portions. First and second bag separating perforation lines are formed widthwise across the outer and inner sheet portions. A user may tear one bag away from the roll of bags by using the bag separating perforation line. The user may then deploy the handles of the bag by tearing along the handle perforation lines.

A method includes a bag forming process with a bag wicketing machine having a sideweld seal head that receives plies of web material, conveys the plies through the sideweld seal head, seals the plies together, cuts the plies to form a bag blank, and moves the bag blank onto an exit conveyor. Pressurized air from nozzles of a pneumatic blow down bar is directed at the bag blank. With an energized laser operatively mounted on the pneumatic blow down bar, the position of the pneumatic blow down bar relative to the bag blank and the exit of the sideweld seal head is adjusted so that a beam emanating from the laser is positioned against the bag blank at a desired location where pressurized air from the nozzles of the pneumatic blow down bar is directed against the bag blank and forces the bag blank into engagement with the conveyor.

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 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 method of manufacturing a bottom gusseted pouch is provided. The method comprises unwinding a pouch webbing in a first flow direction, the pouch webbing defining front and back panels; inserting a gusset webbing between the panels in a second flow direction; attaching the gusset webbing to the panels to form a bottom gusseted end; optionally inserting a closure mechanism between the panels in a third flow direction; attaching the closure mechanism to the panels to form the resealable top end of the pouch; sealing the side edges of the panels to complete the pouch; and optionally cutting the completed pouch from the pouch webbing. At least one of the pouch webbing and the gusset webbing is formed of a supported film.

An apparatus for simultaneously separating a portion of a continuous web of film, having a leading edge and a plurality of spaced apart side seals, includes a base, a plurality of blade pairs, and a film guide device. The blade pairs are moveable between an open and closed positions and are mounted to the base and spaced apart a distance corresponding to the side seals in the film. The film guide device includes a guide member that releasable attaches to a portion of the film adjacent the leading edge. The guide members suspends the film between the plurality of blade pairs in the open position to align the plurality of seals on the film with the plurality of spaced apart blade pairs to accurate separate the film into a plurality of pouches upon movement of the blade pairs to the closed position.

A machine for processing a web of material into bags includes several sections for processing the web of material into bags. An input section is configured to receive a roll of the web of material, a sealing section is configured to form seals in the web of material, and a winder section configured to wind the bags into rolls of bags may be included. A bander section configured to band each roll of bags may be included. A hem forming section configured to form a hem in the web of material may be included. A draw tape unwind station for unwinding draw tape for bags may be included. Related methods are further disclosed.

A bagmaker interoperable with an item processor is disclosed, the bagmaker being configured to produce bags for packaging items for sterilization, such as medical instruments. The bagmaker may include a controller interoperable with a bag production device, the bag production device including a bag cutter and a heat sealer, such that tubing may be sealed and cut, such that a bag of a specified length is formed. Operation of the bagmaker may include identifying tubing corresponding to a bag width of the bag, advancing tubing to correspond with the length of the bag, sealing at least a first end of the tubing, and then advancing and cutting the tubing; ejecting the bag from the bagmaker and retracting remaining uncut tubing, wherein the retraction and ejection may occur contemporaneously or interchangeably in order.
