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.
Claims26
A newsprint core brake system for a continuous running roll press wherein a full and fractional part roll of newsprint web is supplied from newsprint core chucking spindles on an axis indexed into a running newsprint roll core position, and including;
- a web tension sensor means with regulator means for increasing and decreasing a fluid pressure in a line according to the running web tension between the running newsprint roll and the roll press,
- at least one fluid pressure responsive brake means for each fractional part of the newsprint roll and coupled to a newsprint roll core chucking spindle in the running newsprint roll core position,
- the at least one fluid pressure responsive brake means being selectively connected by valve means to said regulator means fluid pressure line for alternately restraining and releasing a selected fractional portion of newsprint roll core rotation responsive to said regulator means fluid pressure.
A newsprint core brake system for a continuous running roll press wherein newsprint web is supplied from a reel apparatus having a central shaft disposed on an indexing axis and having spaced multi-armed spiders with newsprint core chucking spindles on axes positioned radially of and circumferentially spaced about said central shaft for rotatably indexing one of said chucking spindle axes from a pre-drive to a running newsprint roll core position, and including;
- a web tension sensor means with regulator means for increasing and decreasing a fluid pressure in a line according to the running web tension between the running newsprint roll and the roll press,
- a pre-drive means for accelerating a new cored newsprint roll to the running web velocity of an expiring newsprint roll,
- a paster-cutter means for adjustment into close proximity to the running web and to the new cored newsprint roll running at the web velocity of the expiring newsprint roll for splicing thereof to the web of the expiring newsprint roll,
- a fluid pressure responsive brake means coupled to core chucking spindle at each core chucking spindle axis,
- the fluid pressure responsive brake means being collectively connected to said regulator means fluid pressure line for alternately restraining and releasing the newsprint role core rotation at each core chucking spindle axis responsive to said regulator means fluid pressure.
A newsprint core brake system for a continuous running roll press wherein a full and fractional part roll of newsprint web is supplied from a reel apparatus having a central shaft disposed on an indexing axis and having spaced multi-armed spiders with newsprint core chucking spindles on axes positioned radially and circumferentially spaced about said central shaft for rotatably indexing one of said chucking spindle axes from a pre-drive to a running newsprint roll core position, and including;
- a web tension sensor means with regulator means for increasing and decreasing a fluid pressure in a line according to the running web tension between the running newsprint roll and the roll press,
- a pre-drive means for accelerating a new cored newsprint roll to the running web velocity of an expiring newsprint roll,
- a paster-cutter means for adjustment into close proximity to the running web and to the new cored newsprint roll running at the web velocity of the expiring newsprint roll for splicing thereof to the web of the expiring newsprint roll,
- at least one fluid pressure responsive brake means coupled to a core chucking spindle at each core chucking spindle axis,
- the at least one fluid pressure responsive brake means being collectively connected to said regulator means fluid pressure line for alternately restraining and releasing a selected fractional portion of the newsprint roll core rotation at each core chucking spindle axis responsive to said regulator means fluid pressure.
A reel apparatus and newsprint core brake system for a roll press wherein newsprint web is supplied from a newsprint roll core rotatably indexed to a running newsprint roll core position, and including;
- a central rotatable shaft disposed on an indexing axis and having spaced multi-armed spiders with newsprint core chucking spindle axes positioned radially of and circumferentially spaced about said central shaft for rotatably indexing one of said chucking spindles to a running newsprint roll core position,
- a web tension sensor means with regulator means for increasing and decreasing a fluid pressure in a line according to the running web tension between the running newsprint roll and the roll press,
- a fluid pressure responsive brake means coupled to a core chucking spindle at each core chucking spindle axis,
- the fluid pressure responsive brake means being collectively connected to said regulator means fluid pressure line for alternately restraining and releasing the newsprint role core rotation at each core chucking spindle axis responsive to said regulator means fluid pressure.
