请老师帮忙看这句话的翻译和句子结构：

Once the actor ceases to be the dominant element in production, having no longer to 'make a speech', he recedes into the background to take his place among his co-workers, the various other poetic-musical devices, ready to follow the convolutions resulting from the momentary importance of any one of them as they are brought into play. 

上面这句话我主要是对convolution这个词很陌生，查字典查到的意思是“卷积”，但我不是很明白，所以不敢确定后半句自己理解是是否正确，故而来向老师们请教。
