Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
182 words
A semiautomatic line for producing foot-wear with the bottom attached by any one of the cementing, directmoulding or valcanizing methods, said line comprising: process machines including working mechanisms, said machines being arranged according to the sequence of flowsheet procedures; an intermittent-action, vertically-closed conveyer including means adapted to feed shoe uppers to the working stations of said process machines; a hydromechanical drive for said conveyer; supports detachably mounted on said conveyer; lasts mounted on said supports and including means adapted for positioning shoe uppers thereon; working mechanisms of said machines; a hydraulic drive being interconnected with said working mechanisms and with said hydromechanical drive of said conveyer; individual control units for each machine; and a device including means adapted to control the operation of the machines in said line, said device being formed essentially of said control units mechanically interconnected and associated with said hydromechanical drive; said semiautomatic line being subdivided into sections; each of said sections incorporating one of said machines with an individual control unit, a portion of said conveyer corresponding to said machine, and ways for mounting said conveyer portion.
Claim 2
Dependent Claim
182 words
A semiautomatic line for producing foot-wear with the bottom attached by any one of the cementing, directmoulding or valcanizing methods, said line comprising: process machines including working mechanisms, said machines being arranged according to the sequence of flowsheet procedures; an intermittent-action, vertically-closed conveyer including means adapted to feed shoe uppers to the working stations of said process machines; a hydromechanical drive for said conveyer; supports detachably mounted on said conveyer; lasts mounted on said supports and including means adapted for positioning shoe uppers thereon; working mechanisms of said machines; a hydraulic drive being interconnected with said working mechanisms and with said hydromechanical drive of said conveyer; individual control units for each machine; and a device including means adapted to control the operation of the machines in said line, said device being formed essentially of said control units mechanically interconnected and associated with said hydromechanical drive; said semiautomatic line being subdivided into sections; each of said sections incorporating one of said machines with an individual control unit, a portion of said conveyer corresponding to said machine, and ways for mounting said conveyer portion.
Claim 3
Dependent Claim
68 words
A semiautomatic line as claimed in claim 1, wherein each of said control units of the machine incorporated into the line, comprises a drive shaft having a hollow sleeve which is rotatably mounted to control the machine operating cycle, said sleeve carrying disks with change cams adapted to interact, through a train of levers, with connecting rods of hydraulic valves controlling the movement of the machine working mechanisms.
Claim 4
Dependent Claim
41 words
A semiautomatic line as claimed in claim 2, wherein each disk of said control units has a side surface of projection adapted to interact with the lever for positive 14 returning of the hydraulic valve connecting rod to an initial position.
