Definitions

  • the present invention relates to a method and a machine for making bags such as square bottom bags, having flat handles made of folded, cut, glued materials.
  • Bags are used, in particular in commerce, for customers to take their purchases. Such bags are sometimes made of paper, partially or totally, and have a tubular part open at one end and closed at the other end by a bottom, for example of rectangular or square shape. These bags are called square bottom bags. Some of these bags are fitted with handles so that they can be easily transported.
  • the handles are developed on a fixed station. During this development, the legs of the handles are oriented in the direction of travel of the strip. The legs are clamped between a cylinder which guides the belt and a segment transport. The drive of the handles is brutal, the handles having to change from a very low speed to the running speed of the web very quickly. This insertion of the handles is a cause of limiting the production rate of the bags.
  • the handle is formed on a rotating drum, the periphery of which is tangent to the path of the wall.
  • the drum receives along a generator a strip of previously cut material forming a strap which it maintains at two points.
  • the strap is retained during the rotation of the drum so as to fold it near the holding points in an oblique fold and form the legs of the handle at right angles to a cross member held between the two holding points.
  • the legs of the handles are folded back on themselves by a folding station to form a base, before being deposited and glued by the base to the wall of the bag.
  • a blade carried by a folding roller marks the fold on the legs, which raises the bases.
  • a folding bar that moves faster than the periphery of the drum drives the bases to fold them over the legs.
  • Retaining means temporarily fix the handle along the wall of the bag, until the user of the bag goes against these retaining means to deploy the handle.
  • this arrangement does not allow reinforcement sheets to be fitted since the space normally covered by such sheets is already occupied by the folded handle. Thus, the load admitted by such bags is limited.
  • one acts against the provisional holding means by moving the handles away from one another. In the end, a concentrated traction is exerted in particular on the bonding of the base to the wall at the junction with the rest of the handle. This concentration of traction is liable to initiate rapid tearing at this level either of the wall or of the bonding.
  • the invention therefore aims to provide a method of manufacturing a bag provided with handles with or without reinforcing sheets allowing high speeds and a machine implementing such a method.
  • the handle placed on the wall has its legs forward and crosses it backwards as shown in figure 7a .
  • the legs are glued to the wall and the crossbars are located beyond the edge of the bag.
  • the installation can be done before the separation of the bags, on the inside or outside of the bag.
  • the wall is first cut transversely so that the handles are placed over these notches, the final cutting of the bag being carried out in the extension of the notches.
  • two handling stations are used, arranged side by side or offset longitudinally.
  • the laying can also be done after the separation of the hose into sections, before or after the formation of the bottom on the sections, and in this case typically outside them.
  • the cross member of the handle is gripped by the turning drum tangent to the periphery of the laying drum, and through a blade carried by the turning drum, the end of the legs is introduced. in a clamp of the laying drum and the cross member is released by bringing the handle against the periphery of the laying drum.
  • the turning is done in the continuity of the rotation of the laying drum and that of the turning drum. No sudden acceleration is imparted to the handle in this operation, which makes it possible to obtain a high rate.
  • the cross member is moved away from the periphery of the laying drum by the turning drum. By grasping the ends of the legs, the laying drum drives them past the cross member which is retained by the turning drum, so that the legs pass forward.
  • At least one reinforcing sheet is deposited while at least partially covering at least one leg before the handle is turned over. After turning over, the backing sheet will be on the side of the laying drum, then cover the leg (s) being glued to the wall. This technique is applicable for the installation of handles both inside and outside of bags. The connection of the handle with the wall is thus reinforced.
  • the speed of rotation of the laying drum is controlled during a rotation of one revolution to place the handle on the speed of the wall and at the interval between two successive bags. This allows the process to be used to make bags of variable length, not conditioned by the perimeter of the drum. In the period between two successive poses, the speed of the drum is free and can be slowed down to allow a greater length of the wall to pass to make long bags, or on the contrary accelerated to make short bags. The speed is adjusted again during the laying period to match the speed of the wall.
  • the subject of the invention is also a machine for manufacturing bags with handles comprising transport means for passing a wall of the bag along a handle-laying drum mounted to rotate, hooking means for hanging a handle on it.
  • the drum the legs of the handle extending along a perimeter of the drum towards the rear in the direction of rotation of the drum, the legs being connected by a cross member, the hooking means being configured to place the handle on the wall , characterized in that it comprises a turning drum for turning the handle before the handle is placed on the wall and for the legs to be at the front on the laying drum.
  • the turning drum is rotating and tangent to the periphery of the laying drum and includes a cross member clamp for gripping the handle by the cross member as it passes between the laying drum and the drum. reversal and a blade adapted to introduce the end of the legs into a leg clamp of the laying drum, the cross member being configured to release the cross member after the legs are pinched by the leg clamp, the machine further comprising guide means for returning the handle against the periphery of the laying drum after the turning drum and before laying the handle.
  • the machine comprises a station for depositing the reinforcing sheet upstream of the turning drum for deposit at least one reinforcing sheet while at least partially covering at least one leg.
  • the machine comprises control means for controlling the speed of rotation of the laying drum during a rotation of one turn and placing the handle at the speed of the wall and at the interval between two successive bags. .
  • the turning station is completed or replaced by a folding station for folding and folding the legs in two parts one on the other along a folding line, the cross-side part being called the shoulder strap while that the remaining part is called the base.
  • the gluing of the handle to the wall is done by the bases, the cross member being as close as possible to the bottom.
  • the turning station is either dismantled or not used.
  • the turning station can also be transformed into a folding station, as will be seen better below.
  • a guide bar moving faster than the periphery of the drum is used to drive, fold and fold the bases on the shoulder straps.

  • the machine has two stations for placing handles 3, arranged in an offset manner both in the direction of the strip of material 1a and transversely to this direction.
  • the handles 4 are placed on the bags already formed, at the exit of the folding station 7.
