Abstract
An electronically controlled web-slitter includes dual electric motors whose functions may be controlled by an electronic controller accessed either on the chassis of the web-slitter or by way of a computer coupled to the electronic controller. Vertical and side-shift blade set-up and functions are thus accurately controlled.
Claims16
A web-slitter for cutting a web of material, the web-slitter having an upper blade engageable with a lower anvil and comprising:
- a) a carriage assembly adapted for connection to a transverse support bar;
- b) a blade-holder assembly coupled to the carriage assembly and including a side-shift mechanism for moving said upper blade into engagement with said lower anvil;
- c) a first electric motor mounted in said carriage assembly for raising and lowering said blade-holder assembly;
- and
- d) a second electric motor coupled to said blade-holder assembly and having an output shaft coupled to a side-shift piston by a linkage mechanism for moving said blade in a lateral direction.
A web-slitter for cutting a web of material, the web-slitter having an upper blade engageable with a lower anvil and comprising:
- a) a carriage assembly adapted for connection to a transverse support bar;
- b) a blade-holder assembly coupled to the carriage assembly and including a side-shift mechanism for moving said upper blade into engagement with said lower anvil;
- c) a first electric motor mounted in said carriage assembly for raising and lowering said blade-holder assembly;
- and
- d) a second electric motor having an output rod or shaft moveable in a vertical direction and a linkage for converting vertical movement of said rod or shaft into a lateral force to cause said side-shift mechanism to move said blade in a lateral direction toward said anvil.
A web-slitter for cutting a web of material, the web-slitter having an upper blade engageable with a lower anvil and comprising:
- a) a carriage assembly adapted for connection to a transverse support bar;
- b) a blade-holder assembly coupled to the carriage assembly and including a side-shift mechanism for moving said upper blade into engagement with said lower anvil;
- c) first and second electric motors for controlling a vertical stroke of said blade-holder assembly and for controlling said side-shift mechanism respectively;
- and
- d) an electrical sensor circuit for stopping said first motor when said blade holder reaches a predetermined vertical position and a second electrical sensor circuit for controlling the second electric motor for stopping the blade at a predetermined lateral position.
A web-slitter for cutting a web of material, the web-slitter having an upper blade engageable with a lower anvil, comprising:
- (a) first and second electric motors for controlling vertical and side-shift blade movement, respectively;
- (b) an electronic controller having first and second outputs for said first and second motors respectively;
- (c) first and second sensors responsive to the zero positions of said blade in the vertical and horizontal directions of travel, respectively, for providing first control signals to said electronic controller;
- and
- (d) an internal circuit coupling through said blade and said anvil to said electronic controller when said blade is in contact with said anvil whereby to provide second control signals to said electronic controller.
