摘要:
A fabrication machine is disclosed herein. In various aspects, the fabrication machine includes a brake adapted to mechanically cooperate with a wrapper to impart a longitudinal tension to the wrapper by controlling the force required to advance the wrapper, the wrapper comprised of a cellulose-based material. The brake is adjustable to allow selection of longitudinal tension in the wrapper, in various aspects. Various aspects may include a wrapper roll in mechanical cooperation with the brake, the wrapper being drawn from the wrapper roll as the wrapper is advanced. The fabrication machine secures the wrapper at the selected tension about the core to form a structural member, in various aspects. Methods of use of the fabrication machine are disclosed herein. This Abstract is presented to meet requirements of 37 C.F.R. §1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and methods disclosed herein or to delineate the scope thereof
摘要:
A method for making a semifinished product for tubular labels comprises the steps of unwinding a ribbon (3) from a bobbin (4), feeding the ribbon (3) through a compensation magazine (5), inside of which the ribbon (3) temporarily stands, and bending said ribbon (3) into a tubular shape between the step of unwinding the bobbin (4) and the step in which the ribbon (3) stands in the compensation magazine (5). A modular unit (1) for making a semifinished product for tubular labels comprises an unwinding station (2) for unwinding a ribbon (3), a compensation magazine (5) into which the ribbon (3) is unwound waiting for further processing, and a tube-making module (11) arranged between the unwinding station (2) and the compensation magazine (5).
摘要:
Apparatus and method in which a continuous web, having a continuous tear strip extending longitudinally thereof, is formed into a continuous tube, slit simultaneously along opposite sides of the tear strip at intervals spaced longitudinally of the continuous tube, and then severed transversely at locations extending across and inbetween the ends of the slits therein to provide individual sleeves each having a longitudinally extending tear strip for use in effecting sleeve rupture.
