Abstract
Abstract The invention relates to a method of cutting cards from a continuous strip employed in multi-copying, in which the cutting or separation operation is performed by punching. The punching operation is so effected as to first of all remove the active portion of a card while leaving as waste lateral punched strips and intermediate connecting strips between the successive cards and the separated cards and the waste are collected separately and in the order of introduction. The machine comprises principally: a support surface (2) for receiving a pack (3) of cards to be subjected to the cutting operation; an intermittently operable drive mechanism for advancing the cards; a punching mechanism (5) to which the cards to be cut out are brought by the intermittent drive mechanism; a magazine (11) for collecting in the order of presentation the cards which have been cut out and a table (12) for reception of the waste.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A machine for cutting cards from a continuous strip employed in multi-copying by a punching operation comprising a machine frame, a punching mechanism supported by said frame, means for serially advancing a pack of cards to a location for punching in the order of presentation, and means for collecting cards which have been cut out by said punching mechanism, said punching mechanism including a plurality of rods which are vertically slidable in said machine frame, a punch, a frame provided around said punch, a transverse bar coupling said punch to said rods, springs being interposed between said frame and transverse bar to provide an even pressure around the outer periphery of a punched card when the latter has been brought into the punching position.
Claim 2
Dependent Claim
124 words
A machine for cutting cards from a continuous strip employed in multi-copying by a punching operation comprising a machine frame, a punching mechanism supported by said frame, means for serially advancing a pack of cards to a location for punching in the order of presentation, and means for collecting cards which have been cut out by said punching mechanism, said punching mechanism including a plurality of rods which are vertically slidable in said machine frame, a punch, a frame provided around said punch, a transverse bar coupling said punch to said rods, springs being interposed between said frame and transverse bar to provide an even pressure around the outer periphery of a punched card when the latter has been brought into the punching position.
Claim 3
Dependent Claim
55 words
A machine according to claim 1, including a support surface for receiving said pack of cards to be subjected to the cutting operation, said card advancing means comprising an intermittently operable drive mechamism, a magazine for collecting cards which have been cut out in the order of presentation, and a table for reception of waste.
Claim 4
Dependent Claim
17 words
A machine according to claim 2, wherein the intermittently operable drive mechanism comprises chains provided with sprockets.
Claim 5
Dependent Claim
51 words
A machine according to claim 3, in which the chains are driven under the control of a main shaft which carries a pinion provided with teeth around only part of its periphery and engaging a toothed wheel fast with the drive shaft of the wheels about which the chains are driven.
Claim 6
Dependent Claim
41 words
A machine according to claim 4, in which on the input shaft of the drive chains in fixed a cam device, having a notch engageable by a pawl for immobilising the drive chains during the period of stoppage of the latter.
Claim 7
Dependent Claim
80 words
A machine according to claim 4 including means for rocking the long rear side portion of the punch bolster, the said means comprising a cam which is fixed on the main shaft approximately in its centre and which acts through a roller carried by a bent lever fast with the rear side portion for causing pivoting of the rear side portion, adjustment of the cam ensuring rocking of the precise moment of passage of a small tongue remaining after cutting.
Claim 8
Dependent Claim
71 words
A machine according to claim 1 in which the punching mechanism is contructed so that cutting takes place in two stages, in the first stage a card is brought under said cutting punch and stopped under the latter due to the stoppage of the drive mechanism and in the second stage the periphery of the card is held by said frame during the stroke of the punch which performs the cutting.
Claim 9
Dependent Claim
52 words
A machine according to claim 1, in which for the control of the cutting operation, two cams are keyed on the main shaft for action on horizontally arranged levers at the ends of which are pivoted arms which are pivotable about fixed axes, the vertically slidable rods being mounted on the levers.
Claim 10
Dependent Claim
71 words
A machine according to claim 8, in which in a first stage of the cutting a punched card is brought under the cutting punch and immobilised due to the stoppage of said card advancinG means, and in a second stage lowering of the punch is effected under the control of the cams, the levers and the rods, during the downward motion the periphery of the card being held by the frame.
Claim 11
Dependent Claim
31 words
A machine according to claim 9 in which the rods carry means which permit temporary raising of the frame upon advancing of a card before it is stopped under the punch.
