Hand-held labeler

A hand-held labeler for printing and applying labels releasably secured to a carrier web of a composite label web, comprising:

• a housing having a handle, means on the housing for supporting a supply roll of a composite label web, a thermal print head, a platen cooperable with the print head for effecting printing on the labels, means for providing a path for the composite label web from the supply roll to between the print head and the platen, means for delaminating printed labels from the carrier web, means for applying printed labels, means for advancing the carrier web to effect delamination of a printed label and to advance the printed label into label applying relationship with the label applying means, means for applying a braking force to the composite label web without the use of electrical energy to prevent a printed label from pulling the composite label web from the label supply roll during application of a printed label to avoid misregistration of the next label with respect to the thermal print head, means for removing the braking force to enable the carrier web to be advanced by the advancing means, and wherein the means for removing the braking force includes an electromagnetic device and means effective only after the electromagnetic device has operated for a predetermined period of time and including a lost-motion connection for utilizing momentum of the electromagnetic device in the removal of the braking force.
