Abstract: A plurality of similar winding units which are independently rotatably mounted are arranged in vertical superposition on a common support column. Each winding unit comprises a substantially horizontal discoidal support element or plate. Connected thereto is a substantially annular winding drum or mandrel or core. A conveyor delivers the printed products to be wound upon the winding cores. The conveyor comprises an exit or discharge region which is adjustable in height or elevation. A turning device is located adjacent to this discharge region and, together with the discharge region, is adjustable in elevation or height for uprighting or raising into a vertical position the reclining imbricated formation of incoming printed products. Subsequent to the uprighting of the printed products, the printed products are guided to the winding core or the respective wound product package or storage coil formed thereon by means of a pivotable rocker conveyor and are wound or coiled up.

Abstract: A heating wire embedded in any one of several types of shaped elements is fed current by an electrical control apparatus for a time interval which is a function of the ohmic resistance of the wire and the type of shaped element. The type and resistance are automatically determined in advance by measurement of the wire impedance which indicates type and of the ohmic resistance. Welding time is selected from a predetermined directrix depending on resistance, and the directrix itself is chosen on the basis of type by the impedance measurement. A count representative of the time is stored in a counter and pulsed down to zero while current is delivered.

Abstract: Printed products arriving in an imbricated formation are coiled or wound on edge, i.e., with an edge standing upright, onto a revolvingly driven hollow winding cylinder or core. The axis of rotation of this winding core is vertical or is inclined from the vertical. On the underside or bottom side of the winding core there is positioned a co-rotating discoidal support element or plate. The printed products rest or bear with their lowermost edges on this co-rotating support plate. These lowermost edges of the printed products extend substantially transverse relative to the axis of rotation of the support plate. A support strap or element is coiled or wound conjointly with and on the outer side of the imbricated formation of printed products. This support strap or element supports the printed products of the outermost winding or layer of the wound product package or storage coil.

Abstract: A process for manufacturing porous textile substrates impregnated with thermoplastic polymeric pastes, especially fleeces or mats, with subsequent gelling out of polymeric paste, which comprises penetrating impregnating one side of a textile substrate with an evacuated paste comprised of a vinyl polymer and/or copolymers of vinyl chloride, while effecting complete displacement of air through the paste and compactly impregnating said substrate.
