    • A coating apparatus is disclosed for applying a co­ating material (20) to the surface of a paper web (16). The coating apparatus includes a backing roll (12) and an applicator roll (14) which cooperates with the backing roll (12) for defining therebeteween a gap (G1) for the passage therethrough of the web (16). The backing roll (12) and applicator roll (14)counter-rotate at given speeds and a nip roll (18) movably cooperates with the backing roll (12) for defining therebetween a nip section (NS 1). The nip section (NS1) is disposed downstream re­lative to the gap (G1) such that the web (16) extends pro­gressively through the gap (G1) and through the nip sec­tion (NS1) so that the coating material (20) is applied to the surface of the web (16) during passage of the web through the gap (G1) and nip section (NS1).
    • 公开了一种用于将涂料(20)施加到纸幅(16)的表面上的涂布设备。 涂覆设备包括背衬辊(12)和与背衬辊(12)配合的涂布辊(14),用于限定纸幅(16)穿过其中的间隙(G1)。 背衬辊(12)和涂布辊(14)以给定的速度反向旋转,并且夹持辊(18)可与背衬辊(12)可移动地配合,以在其间限定压区部分(NS1)。 辊隙部分(NS1)相对于间隙(G1)设置在下游,使得腹板(16)逐渐延伸穿过间隙(G1)并且通过辊隙部分(NS1),使得涂覆材料(20)被施加到 在幅材通过间隙(G1)和压区部分(NS1)期间,幅材(16)的表面。

    • A roll-type coater for applying a coating material to a web of paper (30) includes an actuator mechanism for accurately controlling the movement and position of a metering roll (14) with respect to a coating transfer roll (22). to prevent shock loading of the transfer roll upon closing movement of the metering roll (14), and to provide for rapid opening of the metering roll when necessary. The mechanism includes a bellcrank (50) and link (52) connected to move the metering roll (14) along guideways (11), in which the linkage approaches, but does not exceed, an overcenter position just before the metering roll comes into contact with one or more micrometer blocks which space it accurately from the coating roll. A movable stop (70) is provided which engages the bellcrank (50) just prior to closing of the rolls, to absorb the impact and prevent the same from being transferred to the adjacent rolls and retracts, permitting final rotation of the bellcrank and the associated movement of the metering roll into its final metering position, with the loads all stacked in one direction. The movable stop may be operated against the bellcrank to open up the nip between the rolls, when necessary.
    • 用于将涂料涂覆到纸幅(30)上的辊式涂布机包括用于精确控制计量辊(14)相对于涂布转印辊(22)的移动和位置的致动机构。 以防止在关闭计量辊(14)的运动时传送辊的冲击载荷,并且在必要时提供计量辊的快速打开。 该机构包括连接成使计量辊(14)沿着导轨(11)移动的曲拐(50)和连杆(52),其中连杆接近但不超过计量辊即将接触之前的偏心位置 带有一个或多个测微计块,可将其与涂布辊精确分离。 设置一个可移动的止动件(70),它恰好在关闭辊之前接合曲拐(50),以吸收冲击并防止冲击传递到相邻的辊并缩回,从而允许曲拐和相关联 计量辊移动到最终的计量位置,所有的负载都在一个方向上堆叠。 必要时,可移动的止动件可以靠着曲拐运行以打开辊之间的辊隙。
