A PU printing method and system including a textile component; and a rotary screen device component. More specifically, the system can include: a source of PU material; a rotary screen containing a squeegee blade or magnetic roller that is connected to the PU material source; means to carry the textile in proximity to the rotary screen and in position to receive a print; and a source of pressure, hydrodynamic or magnetic, to force the PU through the rotary screen and onto the textile.

A manufacturing system for applying a material to a workpiece comprising a blade unit having a blade element for selectively moving along first and second axes for applying the material to the workpiece. A reciprocating motor is coupled to the blade unit for reciprocating the blade element along the first axis concurrent with movement of the blade element along the second axis, and a vibration detector is coupled to the blade unit for detecting the vibrational movement of the blade element. The vibration detector generates an output signal corresponding to the vibrational movement of the blade element. A control unit is coupled to the vibration detector for generating an output signal in response to the vibration detector signal, and a regulating device adjusts a parameter of the reciprocating motor in response to the output signal of the control unit.

A screen printing apparatus includes a pair of clampers that clamp a substrate, a mask plate contacted to the substrate, a pair of squeegees provided above the mask plate vertically, and a squeegee controller that selectively controls one of the pair of squeegees to move in the horizontal direction in abutment against the mask plate so that the selected one of the pair of squeegees slides on the mask plate.

A screen printer in which a squeegee is lowered towards a screen when the internal pressure of a second air chamber of a pressing force adjusting air cylinder is decreased. A control section performs control of an air regulator based on response times from starting control of the air regulator to decrease or increase the internal pressure of the second air chamber until a value detected by a pressure sensor reaches a target value of the internal pressure.
