Abstract: Combined newsprint core brake system and newsprint supply reel in a continuous running roll press, for full and fractional running web supply, web tension sensor control braking coupled to core chucking spindles in the running newsprint roll core position, characterized by selectively activated Zero stroke multi caliper disc brakes carried by multi-armed spiders with core chucking spindles axially positioned and circumferentially spaced for indexing a chucking spindle axis from pre-drive to running newsprint roll core position; eliminating the prior art “transition period” replaced herein by “Constant Tension”, eliminating the prior art drag-belt deterioration of the newsprint surface texture; and with assurance of effective roll to roll splicing.

Abstract: A cylinder for a printing press in which the gap for receiving the ends of a plate or blanket is skewed at an angle with respect to an axial length on the surface of such cylinder such that streaking of the printed product as is visible to the human eye is essentially eliminated. Such improved cylinders have a linear skew width greater than the linear gap width with the trailing end of the trailing edge of the gap being located opposite a non-gap area of the other of such cylinders cooperable therewith when such gaps are in their full overlying position. Such improved cylinders have a non-rotative relative motion when the gaps cross over each other such that the cylinders gradually enter into a zone of decreased pressure therebetween and gradually exit from such zone whereby axial deflection of the cylinders is minimized. Such improved cylinder is particularly suited for a blanket cylinder, a pair of blanket cylinders or plate cylinders or the well known combinations of blanket and plate cylinders.
