Abstract
Abstract Stripping apparatus to remove scrap around die cut blanks in a web (14) comprises a roll pair (10-12) through which the web (14) is passed, one roll (12) carrying spikes (44) to impale the scrap pieces and the other roll (10) carrying abutments (18) to contact the scrap pieces on the opposite side to the spikes. The abutments (18) are retractable, so that effectively the scrap piece is pinched between the spike (44) and abutment (18) shortly before the nip of the rolls (10-12).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
78 words
Stripping apparatus comprising a spike (44, Figure 3) carried by one roll (12) of a roll pair, characterised by the provision of a co-operating abutment (18) carried by the second roll (10) cf the pair, the spike and abutment being synchronised so as to contact the scrap piece on opposite faces of the same in advance of the nip between the rolls, and the abutment being retracted from projection beyond the roll surface as it approaches the nip.
Claim 2
Dependent Claim
78 words
Stripping apparatus comprising a spike (44, Figure 3) carried by one roll (12) of a roll pair, characterised by the provision of a co-operating abutment (18) carried by the second roll (10) cf the pair, the spike and abutment being synchronised so as to contact the scrap piece on opposite faces of the same in advance of the nip between the rolls, and the abutment being retracted from projection beyond the roll surface as it approaches the nip.
Claim 3
Dependent Claim
29 words
Stripping apparatus as claimed in Claim 1 characterised in that the abutment (18) is tubular so that the spike can be received in its bore when impalement is complete.
Claim 4
Dependent Claim
38 words
Stripping apparatus as claimed in Claim-1 characterised in that the retraction is controlled by a cam (36) shaped so that the abutment end sweeps along a straight line tangential to the roll surface and coplanar with the web.
Claim 5
Dependent Claim
52 words
Stripping apparatus as claimed in Claim 1 wherein the spike (44) is surrounded by a tubular end part (46) which is spring driven radially inwardly of the roll (12) and means (48) are provided for driving said end part outwardly at a position angularly spaced from the nip for disengaging impaled scrap
Claim 6
Dependent Claim
22 words
Stripping apparatus as claimed in Claim 4 wherein said means comprise an eccentric driven at the same speed as the roll (12).
