Abstract: A frame that folds to a compact, folded, generally flat shape, and that unfolds to an A-frame with spool-receiving bars hung preferably on both the front side frame and back side frame of the A-frame. The spool-receiving bars are removably received in the cradle spaces of open-topped brackets that extend from the frames. Preferably, no connection is made between the A-frame and the bar or spools, except that the bar rests securely in the brackets due to gravity. Each bar has at least one, and preferably only one, set of radial plates near one end. The plates are spaced to abut the sides of the bracket and/or the side surfaces of the preferred square tubing of the frame legs, so that the plates prevent axial movement of the bar so that the bar ends do not slide or fall out of the brackets. The plates may be sized to also act as a retainer for holding the spools from falling off of that end of the bar when the bar-spool unit is being removed from the caddy and transported or otherwise handled.

Abstract: A machine for winding film, a method of manufacturing spools of pre-stretched film, and spools of pre-stretched film obtained as a result, are disclosed. The method of winding spools of pre-stretched stretchable film includes importing oscillation to the film with a component perpendicular to the axis of the film. For example, during pre-stretched and winding of the film on a take-up spool, a feed spool, i.e. a spool from which the stretchable film for stretching is taken, is caused to oscillate, and/or the take-up core is caused to oscillate. This ensures that successive layers of film are offset, in particular at the margins of the film. Spools of film obtained in this way do not have portions of extra thickness and lower tension at the margins as is the case prior art spools of pre-stretched film.

Abstract: A recording device operable with continuous paper in the form of a roll includes a pair of drive rollers for selectively rotating the roll in the forward direction for paying out the paper or in the reverse direction. A controller causes the drive rollers to rotate in the reverse direction in response to a preselected signal. Bar codes representative of serial numbers are printed on one side edge of the paper. While the roll is rotated in the reverse direction, a number identification circuit reads the bar codes 41 and detects the leading edge of the paper on the basis of one bar code positioned at the leading edge and another bar code adjoining a roll position which the leading edge overlies. When the number identification circuit detects the leading edge, the controller switches the direction of rotation of the roll from reverse to forward.
