Abstract
Abstract A machine for imprinting on a strip or sheet comprises multiple printing cylinders in tandem and revolving continuously at the same speeds for imprinting successive impressions on the strip. The strip is intermittently fed at a linear speed that is the same as the peripheral speed of the impression surfaces of the printing plates on the printing cylinders. The mechanism for intermittent feed comprises a carrier having spring fingers that engage notches at the sides of the strip to feed the strip a predetermined amount after which the carrier is returned to an initial or starting position for again feeding the strip.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
222 words
A machine for imprinting on a sheet of material, said machine comprising a frame, a plurality of printing cylinders spaced along said frame, each printing cylinder mounting a printing plate and an impression roller for imprinting successive impressions on said sheet as the sheet moves between each printing plate and its associated impression roller, means for revolving said printing cylinders continuously and at the same peripheral speed, and means for intermittently feeding said sheet such that when a printing plate is In printing contact with said sheet, the peripheral speed of the printing plate is the same as the speed of travel of the sheet; said intermittent feeding means comprising a carrier for engaging said sheet at predetermined regions thereof, and means for moving said carrier a predetermined amount to advance said sheet a predetermined distance to maintain the register of the printing plates on the sheet; said intermittent feeding means further including a rotatable member, a flexible structure trained over said rotatable member and connected to said carrier and to said rotatable member, first means for rotating said member in one direction an amount sufficient to advance said carrier said predetermined amount from an initial position of the carrier, and second means for rotating said member a like amount in the opposite direction to return said carrier to its initial position.
Claim 2
Dependent Claim
222 words
A machine for imprinting on a sheet of material, said machine comprising a frame, a plurality of printing cylinders spaced along said frame, each printing cylinder mounting a printing plate and an impression roller for imprinting successive impressions on said sheet as the sheet moves between each printing plate and its associated impression roller, means for revolving said printing cylinders continuously and at the same peripheral speed, and means for intermittently feeding said sheet such that when a printing plate is In printing contact with said sheet, the peripheral speed of the printing plate is the same as the speed of travel of the sheet; said intermittent feeding means comprising a carrier for engaging said sheet at predetermined regions thereof, and means for moving said carrier a predetermined amount to advance said sheet a predetermined distance to maintain the register of the printing plates on the sheet; said intermittent feeding means further including a rotatable member, a flexible structure trained over said rotatable member and connected to said carrier and to said rotatable member, first means for rotating said member in one direction an amount sufficient to advance said carrier said predetermined amount from an initial position of the carrier, and second means for rotating said member a like amount in the opposite direction to return said carrier to its initial position.
Claim 3
Dependent Claim
37 words
A machine according to claim 1 including third means actuated upon rotation of said member said amount for rendering ineffective the operation of said first means so that said second means then operates to return said carrier.
Claim 4
Dependent Claim
34 words
A machine according to claim 2 in which said first means includes a drive member and an electrically operated clutch, and said third means is a switch for controlling the current to said clutch.
Claim 5
Dependent Claim
28 words
