  • Patent number: 4832677
    Abstract: A method and apparatus for forming draw tape bags wherein the bag material moves continuously during the manufacture, except for the last step. The apparatus may be used with an in-line system wherein a tube is extruded and a side gusset is formed to create a hem; or the apparatus may be used with an off-line system wherein folded bag material is used, and a continuous hemmer is provided to turn the loose edges. In the off-line system a constant tension dancer precedes the hemmer to maintain constant tension on the web regardless of the size of the supply roll. The web continues to move, and a cutter is actuated to move through a circle and engage the web to punch finger holes in the hem. A reel of a strip of material is continuously fed, the strip being slit longitudinally to provide the draw tapes which are inserted into the hems. A tape guide tensions the tape and assures that the tape is well within the hem, the hems are sealed, and the bags are side welded.

  • Patent number: 4820251
    Abstract: A bag forming apparatus passes a hemmed web through a rotating edge notcher and related units to form a taped hem in the web which is passed through an intermittently operated bag making machine. A web supply unit includes a web take-up unit to maintain a constant tension in the continuously moving web to the bag making machine. The web notches are phased with the bag making machine to locate the notches centrally of each bag. During starting and stopping, the web take-up unit changes the web length moving through the notching unit at normal full web speed operation and the web length variations are minimal. A programmable notch controller actuates a stepper motor to rotate the notcher. The controller responds to a control signal to form a notch. A programmable switch is coupled to the bag making machine to generate a first control signal for each bag cycle and is phased with the full web speed to locate the notch centrally of the bag.

  • Patent number: 4775358
    Abstract: In a multi-bobbin machine for making paper booklets e.g. of interleaved cigarette paper, a multiplicity of strips from respective supply bobbins are interfolded and converged to form a booklet strand which is cut to length by a cutting station which reciprocates along the strand so that booklet lengths enter it and are cut. A rotating non-circular shaft passes through the cutting station and a sleeve in the cutting station slides axially along the shaft as the station reciprocates and rotates with the shaft. The sleeve is independently linked to a strand clamp and to a cutting knife which are separately timed and move along different paths, the strand clamp moving longitudinally towards and away from the strand while the knife makes a slicing movement across and through the strand.

  • Patent number: 4650453
    Abstract: A flexible web which is caused to run through a cross cutter to be severed at regular intervals in order to yield a series of discrete sections is engaged by a pair of holders which attract the web by suction immediately behind the severing plane when the cutter severs the web. The holders advance with the web and thereafter with the freshly formed section to prevent changes in orientation of the sections on their way to a removing station where they are expelled from the path of the web by block-shaped commodities which are draped into the respective sections. The surfaces of the holders are small and the length of each holder is a minute fraction of the length of a section, as considered in the longitudinal direction of the web. The holders are mounted on endless toothed belt or chain conveyors which advance the holders along an endless path having an elongated reach extending adjacent to the path of movement of the web and its sections toward, past and beyond the severing station.
