Here you will find an entire free ebook comparing handmade with machine made. It may be far more more information than you want, but it is a fine pictorial resource

You will see at The Rook and The Raven, the five most ubiquitous types of machine-made lace:
Pusher - begun c. 1812, in England (New Radford)
Leavers - begun c.1813, in England (Nottingham)
Barmen - begun c.1890, in Germany
Schiffli - begun c.1890, in Switzerland
Quaker - begun c.1894 as Lehigh, in the USA
After a while, one begins to recognize on which machine the laces were made. Study the photos. All five produce different qualities of lace and different patterns of lace. Some is thin, irregular, crude. Some is so fine it is nearly impossible to tell it from handmade. If you are a lace-maker, however, you can follow the trail of the thread and know instantly. Some machines can produce lace that beautifully mimics scores of different handmade lace – especially Schiffli. They are masters of replication.
