Abstract: A machine for producing a tubular product by helical winding of strips of web material including a mandrel and a winding member to helically wind the strips of web material around the mandrel is disclosed. To improve adhesion between the strips, at least one pressure member is provided, cooperating with the mandrel, disposed downstream or upstream of the winding member with respect to the direction of advance of the tubular product being formed on the mandrel. The pressure exerted by the pressure member promotes adhesion of the strips forming the product.

Abstract: A machine for producing tubes by winding into a spiral two or more overlapping and staggered strips of a ribbon-shaped material on a spindle, having a winding unit which winds into a spiral two or more overlapping and staggered strips of a ribbon-shaped material on the spindle and causes the tube formed from the material to advance continuously, and a cutting unit fitted with rotating tube cutters and provided with a reciprocating motion along the direction of advance of the tube to cut the tube into sections of predetermined length during the advance of the tube. The cutting unit is associated with members for driving the rotating cutters, which impart to the rotating cutters a rotary motion derived from the reciprocating motion of the cutting unit.

Abstract: A tube positioning apparatus has at least one mandrel for positioning tubes for processing. A variable tube positioning stroke length is facilitated for optimizing stroke length and for optimizing the time required to position and process tube, such as by cutting. The tube positioning apparatus comprises a slide block having a mandrel attached thereto. The slide block is actuated on a plurality of slide rails from a first position to a second position. In the first position, the mandrel is retracted and in a second position the mandrel is extended for access by processing tools, such as circular knives for cutting the tube into desired lengths. A programmable sequence timer is provided for establishing desired time intervals during which the slide block and attached mandrel are in the retracted position or the extended position.

Abstract: A method of manufacturing a yarn carrier designed to accommodate the tail of the yarn to be wound therearound without severing. A tube is wound from paper and a portion severed therefrom, producing a burr. A subsequent grinding operation removes the burr, and forms a beveled region having loose fibers to cushion the yarn against a winding mandrel.

Abstract: Tublar workpieces are formed with perforations of desired size and/or shape by repeatedly piercing selected portions of the workpieces by needles, pins or analogous piercing tools. The tools can be stationary while the workpieces roll therealong, or the workpieces can rotate while coming into repeated engagement with one or more sets of orbiting tools. The frequency and the number of penetrations of tools into selected portions of the workpieces are selected with a view to heat the tools as a result of frictional engagement with the material of the workpieces, i.e., as a result of repeated penetration into and extraction from selected portions of a rotating or rotating and rolling and/or axially moving workpiece. This enhances the making of predictable perforations in tubular workpieces, especially workpieces which consist of a synthetic thermoplastic material, such as bobbins for the storage of textile yarns.

Abstract: Apparatus for continuously applying a spiral wrap around successive cylindrical articles, securing the wrap to the cylindrical articles forming a series of wrapped articles, and subsequently severing individual wrapped articles from the wrapped series of same. Cylindrical articles are deposited onto a conveyor belt along which they are fed in proper alignment and in end to end abutting relationship to a wrapping station. At the wrapping station, a covering material, such as paper or the like is spirally applied to the successive rotating cylindrical articles in continuous fashion. Rotary and forwarding motion is supplied by a drive belt acting on previously wrapped articles which motion is imparted to the individual articles at the wrapping station. Subsequent to the wrapping station, the wrap or cover is secured to the cylindrical article by contact heaters, tunnel heaters, adhesive, or the like.

Abstract: An ice cream tub cutter in which a tub of ice cream is clamped to a turntable between two posts. Adjustable in height sleeves are mounted on these posts, and a knife is mounted on one of them to make an initial cut, this being through the cover of the tub of ice cream and is accomplished by rotation of the turntable with the knife in engagement with the cover. A wire extends between the sleeves at the same elevation as the knife cut, and an adjustably tensioned spring applies tension to the wire to effect cutting the ice cream as the tub of ice cream is rotated a second time.

Abstract: A method and apparatus are disclosed for formation of tubular segments from a generally continuous tube of material by internally cutting the tube of material. The apparatus of the present invention includes a forming mandrel upon which the tube of material to be cut is carried, and upon which the tube is preferably spirally wound. The apparatus further includes a rotary cutter assembly mounted within the forming mandrel. The cutter assembly includes a cutter arbor and a blade actuating rod, with one or more cutting blades of the cutter assembly operatively associated with the actuating rod and the arbor such that relative axial movement of the actuating rod and the cutter arbor moves the cutting blades inwardly and outwardly of the forming mandrel of the apparatus. A cam mechanism is provided for effecting this desired relative axial movement.

Abstract: The paper tube making machine is improved to reduce the floor space required for the installation and operation of the machine and enhance the efficiency of paper tube production by arraying in parallel a plurality of fixed shafts adapted to coil one or two paper tapes thereon and vertically disposing arm plates serving to support at least one endless rolling belt diagonally wound around the fixed shafts.

Abstract: A method of simultaneously flanging and cutting tubular bodies by scoring the tubular bodies on each side of the cut is disclosed.

Abstract: A banding machine for continuously forming and applying the bands on articles comprises means for arranging rows of the articles, means for receiving the articles at the front end of the arranging means and transferring the articles to a band receiving position, means for supplying at least one tubular member to be fabricated into a band, and fabricating and positioning means to continuously fabricate bands from the respective tubular member and secure the bands around the articles retained at the band receiving position by the receiving and transferring means.

Abstract: A process and arrangement for controlling a pipe-cutting device for cutting pipe formed on a continuously operating spiral winding machine which forms a pipe from a band of wound sheet material such as paper. The pipe-cutting device is adapted to move along the formed pipe at a speed corresponding to the feeding speed of the band which is being guidingly fed at a predetermined feed angle toward the pipe-forming spindle of the spiral winding machine. An arrangement is provided in a continuous spiral pipe-winding machine for controlling the movement of a cutting member.

Abstract: Structural improvements in the mechanisms for supporting and driving the blade of an orbital saw. Improvements in the controls for the drive mechanisms for the winder and for the saw blade particularly as to increasing or decreasing the production rate of specified stick lengths.

Abstract: A composite container comprising a tubular body formed of spirally wound plies of paperboard or the like and an internal vacuum accommodating liner substantially coextensive with the length of the tubular body and adhesively affixed solely at the opposed ends thereof to the tubular body. The container is completed by the mounting of opposed end caps which are hermetically sealed to the adhesively secured opposed ends of the liner for the accommodation of an internally developed vacuum within the liner.
