Abstract
Abstract A control device for use in a machine adapted to carry out sequential operations upon articles is shown. The control device activates and disengages a plurality of operating elements and will cause sequential disengagement and activation of the various operating elements as the machine is deliberately started or shut down but will cause simultaneous disengagement of all operating elements if the machine is stopped by reason of malfunction or accident.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
77 words
A control device for a machine adapted to carry out sequential operations upon articles, comprising means for causing sequential activation of operating elements as the articles impinge upon each of said operating elements, and means for causing sequential inactivation of operating elements when the machine is shut down as the last article leaves each of said operating elements, said means causing simultaneous inactivation of said operating elements when said machine stops by reason of malfunction or accident.
Claim 2
Dependent Claim
77 words
A control device for a machine adapted to carry out sequential operations upon articles, comprising means for causing sequential activation of operating elements as the articles impinge upon each of said operating elements, and means for causing sequential inactivation of operating elements when the machine is shut down as the last article leaves each of said operating elements, said means causing simultaneous inactivation of said operating elements when said machine stops by reason of malfunction or accident.
Claim 3
Dependent Claim
17 words
A control device as described in claim 1 said means constituting pneumatic cylinders and control means thereof.
Claim 4
Dependent Claim
18 words
A control device as described in claim 2 said pneumatic cylinders having pistons therein operated from both sides.
Claim 5
Dependent Claim
14 words
A control device as described in claim 3 said control means being magnetic valves.
Claim 6
Dependent Claim
19 words
A control device as described in claim 4 each of said magnetic valves being controlled by a separate relay.
Claim 7
Dependent Claim
61 words
An envelope-making machine comprising, in combination and operative relationship, a printing unit, a gumming unit, a folding unit, and window material applying unit, control means for engaging and disengaging each of said units, and a relay operatively connected to said control means, said relay being actuated if a malfunction occurs in said machine and thereupon simultaneously disengaging all of said units.
Claim 8
Dependent Claim
61 words
An envelope-making machine comprising, in combination and operative relationship, a printing unit, a gumming unit, a folding unit, and window material applying unit, control means for engaging and disengaging each of said units, and a relay operatively connected to said control means, said relay being actuated if a malfunction occurs in said machine and thereupon simultaneously disengaging all of said units.
Claim 9
Dependent Claim
65 words
An envelope-making machine as described in claim 6 including a first sensing device operatively connected with said gumming unit and a second sensing device operatively connected with said folding unit, and second relay means operatively connected with each of saId sensing devices, so that the respective unit will be rendered inoperativE if an article is not in position to be worked on at said unit.
Claim 10
Dependent Claim
16 words
An envelope-making machine as described in claim 7 each of said sensing device being a photocell.
Claim 11
Dependent Claim
41 words
An envelope-making machine as described in claim 8 including third relay means operatively connected with said printing unit, and switch means operatively connected with said air suction means, said switch means being opened when said air suction means are no operative.
