Abstract:
An apparatus automatically forms a paperboard blank into a container having a double glued side wall construction for providing an enhanced strength to the container. A platen drives the blank through mechanically powered forming rails for an initial folding of the blank into a partially formed container having a bottom, end and side walls, and inside corner supports. A compression plate and folding arms are biased against adhesive portions of the partially formed container for forming a fully formed container having a double glued side wall construction.
Abstract:
A laminating apparatus and methods are provided for laminating fabric such as for a disposable garment. The apparatus preferably includes a frame having upper and lower frame regions, a first roll of fabric mounted to the upper frame region so as to provide a first web of fabric when unwound from the first fabric roll, and a second roll of fabric mounted to the lower frame region and positioned adjacent the first fabric roll so as to provide a second web of fabric when unwound from the second fabric roll. A fabric dance controller is preferably positioned downstream from the first and second fabric rolls and positioned to receive the first and second webs of fabric therefrom for dancingly controlling the tension of the first and second webs of fabric being received from the first and second fabric rolls. Additionally, a fabric laminator is preferably positioned downstream from said fabric dance controlling means and positioned to receive the first and second webs of fabric for combiningly laminating the first and second webs of fabric to thereby provide a laminated web of fabric therefrom.
Abstract:
A disposable undergarment forming apparatus and methods are provided for forming disposable undergarments. The apparatus preferably includes a core former positioned to form a stream of undergarment cores. The core former includes a mat securer positioned to secure each of a plurality of undergarment mats to a sheet of a polymeric material and a first separator positioned downstream from the mat securer for separating the stream of undergarment cores into a plurality of individual cores. An elastic waistband former preferably is positioned adjacent the core former for forming elastic waistbands. A waistband securer is positioned downstream from the core former and positioned to receive the elastic waistbands from the elastic waistband former for securing the waistbands to the plurality of individual undergarment cores to thereby form a chain of a plurality of undergarments. A folder is positioned downstream from the waistband securer for folding each of the plurality of undergarments of the chain. A side connector is positioned downstream from the folder for connecting at least the side peripheries of the waistbands of the plurality of undergarments of the chain. The apparatus also preferably includes a second separator positioned downstream from the side connector for separating the plurality of undergarments of the chain into individual disposable undergarments.
Abstract:
An apparatus and method for forming a connection of portions of a moving folded web of disposable undergarments is provided. The apparatus preferably includes a registration conveyor positioned to register and convey a folded web of disposable undergarments moving along a predetermined path of travel and a web connector positioned adjacent the registration conveyor to connect portions of the folded web as the folded web is conveyed along the predetermined path of travel. A method preferably includes registeringly conveying a folded web of disposable undergarments along a predetermined path of travel and connecting portions of the folded web as the folded web is conveyed along the predetermined path of travel.
Abstract:
Spaced seams in a disposable garment web containing a plastic component and moving rapidly along a direction of manufacture is formed by bringing an ultrasonic welder into pressurized contact with the machine web for a predetermined period of time, heating the web along the seam for a first segment of the predetermined period of time and then maintaining pressurization with the ultrasonic welder during a second segment of the predetermined time period without heat sufficient to permit the plastic material to resolidify.
Abstract:
Apparatus for opening flattened cartons having a pair of minor flaps and a pair of major flaps. A constant speed conveyor carries a horizontally disposed flattened carton across an actuator having a cam surface. The cam surface moves upward to fold one pair of major and minor flaps upward and then downward to fold the other pair of major and minor flaps downward. A clamp grasps the upward folded major flap and draws it upward as the conveyor moves the carton forward causing the carton to open. The clamp releases the major flap and the carton moves past a glue gun which applies glue to the minor flaps. A pair of curl bars folds the major flaps against the glue coated minor flaps. An extending platen presses the flaps against a roller bank permitting the glue to set. The platen retracts and the opened and bottom-sealed carton is completed.
Abstract:
The torque-increasing device includes multiple rotating discs, rings, or rotors, each including embedded or affixed magnets. The discs are canted toward each other, thus passing closer to each during the first half of a rotation, and further apart during the second half of a rotation. As the adjacent magnets attract each other, the attractive force is split into two vectors: a vector that is perpendicular to an imaginary plane that divides the discs, and a torque vector that is parallel to the face of the rotors. Disruption of the attraction of the magnets on either the upper or lower half of the rotor, or a segment of the upper or lower half, unbalances the rotors and captures a torque.
Abstract:
A control system for a pneumatically operated toilet includes a valve arrangement and a controller. The valve arrangement includes a plurality of solenoid operated valves. The controller includes a microprocessor in signal communication with the plurality of solenoid operated valves, the controller configured to operate the valve arrangement to independently control operation of a water valve for selectively introducing water into a toilet bowl of the pneumatically operated toilet, operation of a flapper valve operating cylinder for opening and closing a waste opening of the toilet bowl, and pressurized air supply to a waste transfer chamber of the pneumatically operated toilet.
Abstract:
Disposable garments of the training pants variety include a cuff which is rolled inwardly from the plane of each leg opening. The rolled cuff feature is obtained during production by stretching a unitary elastic sheet across the machine web in a direction lateral to the direction of manufacture, and then cutting leg openings through the elastic sheet and an adjacent outer web. The machinery for manufacturing the garments includes various features which facilitate the manufacture of this garment, including a reciprocating cutting knife and an associated accumulating conveyor for providing a reciprocal motion into the reciprocal knife. The manufacturing apparatus also includes features for maintaining core pads in the desired alignment, and various other features.
