Abstract
A label dispenser for peel-off labels pulls a web with peel-off labels attached from a label supply location to a take-up spool. The label dispenser maintains the web in a taut condition when the web passes over a peeling edge by providing first and second rods about which the web wraps in a sinuous flow path on the feed side of the peeling edge. The take-up spool resists turning in the reverse direction to maintain the web in a taut condition. A cam is selectably rotatable about an axis that is spaced apart from the center of curvature at each location on the curved surface that may contact the web to adjust the thickness of the flow path of the web at the peeling edge.
Claims20
An apparatus for dispensing peel-off labels from a roll of peel-off labels or an accordion-folded stack of peel-off labels, the peel-off labels being adhered to a web along a longitudinal direction of the web, the web having a width normal to the web longitudinal direction, the apparatus comprising:
- a. a label supply location and a flow path from the label supply location, the web being movable along the flow path from the label supply location;
- b. a peeling edge, the peeling edge being disposed along the flow path, the flow path having a configuration to peel the peel-off labels from the web at the peeling edge as the web moves along the flow path;
- c. the configuration of the flow path to peel the peel-off labels from the web at the peeling edge comprising a cam disposed along the flow path immediate prior to the peeling edge as the web moves along the flow path from the label supply location, the cam being movable with respect to the peeling edge, the cam being configured to bear on the web immediately prior to the peeling edge as the web moves along the flow path, the configuration of the flow path to peel the peel-off labels from the web at the peeling edge further comprising a change in a flow path direction at the peeling edge, the cam defining the change in the flow path direction at the peeling edge when the cam bears upon the web immediately prior to the peeling edge as the web moves along the flow path, the change in the flow path direction at the peeling edge as the web moves across the peeling edge being user selectable by a movement of the movable cam.
A system for dispensing peel-off labels, the system comprising:
- a. a roll of peel-off labels or an accordion-folded stack of peel-off labels, the peel-off labels being adhered to a web along a longitudinal direction of the web, the web having a width normal to the web longitudinal direction;
- b. a flow path of the web along the web longitudinal direction from a label supply location to a peeling edge, the flow path having a configuration to peel the peel-off labels from the web at the peeling edge, the configuration of the flow path to peel the peel-off labels from the web at the peeling edge comprising a cam disposed along the flow path immediate prior to the peeling edge as the web moves along the flow path from the label supply location, the cam being movable with respect to the peeling edge, the cam being configured to bear on the web immediately prior to the peeling edge as the web moves along the flow path, the configuration of the flow path to peel the peel-off labels from the web at the peeling edge further comprising a change in a flow path direction at the peeling edge, the cam defining the change in the flow path direction at the peeling edge when the cam bears upon the web immediately prior to the peeling edge as the web moves along the flow path, the change in the flow path direction at the peeling edge as the web moves across the peeling edge being user selectable by a movement of the movable cam.
A method for dispensing peel-off labels, the method comprising:
- a. obtaining a roll of peel-off labels or an accordion-folded stack of peel-off labels, the peel-off labels being adhered to a web along a longitudinal direction of the web, the web having a width normal to the web longitudinal direction,
- b. obtaining a label dispenser having a label supply location and a flow path from the label supply location, the web being movable along the flow path from the label supply location, the label dispenser having a peeling edge, the peeling edge being disposed along the flow path, the flow path having a configuration to peel the peel-off labels from the web at the peeling edge as the web moves along the flow path, the configuration of the flow path to peel the peel-off labels from the web at the peeling edge comprising a cam disposed along the flow path immediate prior to the peeling edge as the web moves along the flow path from the label supply location, the cam being movable with respect to the peeling edge, the cam being configured to bear on the web immediately prior to the peeling edge as the web moves along the flow path, the configuration of the flow path to peel the peel-off labels from the web at the peeling edge further comprising a change in a flow path direction at the peeling edge, the cam defining the change in the flow path direction at the peeling edge when the cam bears upon the web immediately prior to the peeling edge as the web moves along the flow path, the change in the flow path direction at the peeling edge as the web moves across the peeling edge being user selectable by a movement of the movable cam;
- c. placing the roll or stack of peel-off labels in the label feeding location;
- d. selecting the change in the flow path direction at the peeling edge by moving the cam with respect to the peeling edge so that the peel-off labels will separate from the web at the peeling edge when the web moves along the flow path from the label supply location;
- e. separating the peel-off labels from the web at the peeling edge by moving the web from the label supply location along the flow path and across the peeling edge.
