    • In a printing device in which a printing material is printed on or applied to a to-be-printed surface of a circuit board through a screen mask for printing having openings formed therein in a predetermined pattern, it is intended to reliably remove cream solder remaining in the openings in the screen mask. After an air suction mechanism (19) has its flow rate controlled by a flow rate controller (20). An air suction section (15) is lifted until its front end contacts with the screen mask (5), the air suction mechanism (19) starts cleaning by sucking air from the openings (6) in the screen mask (5). An inspecting camera (2) is used to observe the cream solder (4) remaining in the openings (6) after cleaning, and the air suction flow rate is controlled according to the results thereof to effect cleaning again.
    • 在印刷装置中,其印刷材料通过其中形成有预定图案的开口的印刷用屏幕掩模印刷在电路板的被印刷表面上或涂布在印刷电路板的被印刷表面上,旨在可靠地除去剩余的膏状焊剂 在屏幕上的开口中。 空气抽吸机构(19)的流量由流量控制器(20)控制。 抽吸部分15被提升直到其前端与屏幕面罩5接触,空气抽吸机构19通过从屏幕面罩5中的开口6吸入空气开始清洗。 检查照相机(2)用于在清洁之后观察剩余在开口(6)中的膏状焊料(4),并且根据其结果控制空气吸入流量以再次进行清洁。

    • An apparatus 1 for widening a foam sheet S obtained immediately after heating and foaming a foam sheet which has not been yet widened, while the foam sheet S is continuously received or supplied. The sheet widening apparatus 1 comprises: a pair of chains 2 constructed in the form of endless chains composed of links 22 having pin parts 21 and a driving device 3 meshing with these chains 2 and driving the chains 2 along such loci as to widen the space between the chains 2 from sheet receiving start points to sheet receving end points. A method for widening a foam sheet by the sheet widening apparatus 1 comprises the steps of piercing both the side parts of the foam sheet S with the pins 21 at the sheet receiving start points; widening the space of width between the pins 21 along gently curved loci by drying the chains 2 while the pins 21 penetrating the foam sheet; and receiving the foam sheet S from the sheet receiving start points to the sheet receiving end points while the foam sheet is widened. The foam sheet S obtained after the widening step in accordance with the sheet widening method.
