Abstract
Disclosed are a printer and a stacker and methods. The printer prints selectively on one or both sides of a printable web and sheets or labels are cut from the web and stacked in the stacker. The printer has an unwind mechanism that accepts and holds web rolls of different widths in center-justified relationship with respect to a print head. The printer has a spindle for mounting an ink ribbon core with a detent for center-justifying the ink-ribbon with respect to the print head.
Claims26
A spindle assembly, comprising:
- a spindle for mounting supply roll cores of different predetermined widths having respective webs of different widths wound thereon, a latch movably mounted on the spindle and having at least two pairs of stepped shoulders engageable with opposite ends of a supply roll core of a predetermined width, and the mounted supply roll core being center-justified on the spindle by and between the engaged pair of shoulders of the latch.
Method, comprising:
- providing a spindle having an axis and at least one pair of connected shoulders movably mounted on the spindle, wherein the spindle is capable of mounting a supply roll having a web wound onto a core, and moving the pair of shoulders in unison transversely with respect to the spindle axis to a position adjacent opposite ends of the core when the core is center-justified with respect to the spindle.
Method, comprising:
- providing a spindle and two connected pairs of shoulders movably mounted on the spindle, wherein the spindle is capable of mounting supply roll cores of different widths having respective webs of different widths wound thereon, and moving the pair of shoulders that corresponds to a core of a predetermined width into straddling relationship to the ends of the core when the core is center-justified with respect to the spindle.
Method, comprising:
- providing a spindle and at least two pairs of connected shoulders movably mounted on the spindle, wherein the spindle is capable of mounting supply rolls with cores of different widths having respective webs of different widths wound thereon, and sliding a supply roll onto the spindle until the supply roll is center-justified on the spindle whereupon the pair of shoulders corresponding to the width of the core are movable into straddling relationship with the ends of the core.
Method, Comprising:
- providing a spindle and at least two pairs of connected shoulders movable mounted on the spindle, wherein the spindle is capable of mounting supply rolls with cores of different widths having respective webs of different widths wound thereon, and sliding a supply roll onto the spindle until the supply roll is center-justified on the spindle whereupon the pair of shoulders corresponding to the width of the core are spring-biased into straddling relationship with the ends of the core.
A spindle assembly, comprising:
- an axially extending spindle for mounting a supply roll core having a web wound thereon, a latch mounted on the spindle for transverse movement and having at least one pair of spaced connected shoulders movable as a unit and engageable with opposite ends of the supply roll Core, the supply roll core being center-justifiable on the spindle and confinable by and between the pair of shoulders.
Method, comprising:
- providing a spindle and at least one pair of Connected shoulders movably mounted on the spindle, wherein the spindle is capable of mounting a supply roll core with a web wound thereon, and sliding a supply roll onto the spindle until the supply roll core is center-justified on the spindle whereupon the pair of shoulders corresponding to the width of the core are movable into straddling relationship with respect to the end portions of the core.
A spindle assembly, comprising:
- an axially extending spindle for mounting a supply roll core having a web wound thereon, a latch movably mounted on the spindle and having opposed connected portions movable transversely in unison and engageable with opposed end portions of a supply roll core, the supply roll core being center-justifiable on the spindle and confinable by and between the opposed connected portions of the latch.
Method comprising:
- providing a spindle for mounting a supply roll core with a web wound thereon and a latch on the spindle having portions engageable with end portions of a core, and sliding the core onto the spindle until the core is center-justified on the spindle whereupon the engageable portions are movable into and out of latching engagement with respect to the end portions of the core.
