Hem

A hem in sewing is a garment finishing method, where the edge of a piece of cloth is folded narrowly and sewn to prevent unravelling of the fabric.

Methods

There are many different styles of hems of varying complexities. The most common hem folds up a cut edge, folds it up again, and then sews it down. The style of hemming thus completely encloses the cut edge in cloth, so that it cannot unravel. Other hem styles use fewer folds. One of the simplest hems encloses the edge of cloth with a stitch without any folds at all, using a method called an overcast stitch, although an overcast stitch may be used to finish a folded "plain hem" as well.

There are even hems that do not call for sewing, instead using iron-on materials, netting, plastic clips, or other fasteners. These threadless hems are not common, and are often used only on a temporary basis.

The hem may be sewn down with a line of invisible stitches or blind stitch, or sewn down by a sewing machine. The term hem is also extended to other cloth treatments that prevent unraveling. Hems can be serged (see serger), hand rolled and then sewn down with tiny stitches (still seen as a high-class finish to handkerchiefs), pinked with pinking shears, piped, covered with binding (this is known as a Hong Kong finish), or made with many other inventive treatments.

Hem (knitting)

A hem in knitting is the edge of a piece of knitted fabric that is parallel to the rows of stitches, as compared to a selvage, which is perpendicular to the hem and rows of stitches. Hems can be made in several ways.

The simplest approach is to bind off, possibly with decorative elements such as picots. This approach adds no extra thickness at the hemline (which is sometimes desirable).

Another approach amounts to a tuck: the fabric is folded over and the stitches are knit together pairwise with the stitches of a previous row. In this approach, the fabric is doubled along the hemline.

Maintenance, repair, and operations

Maintenance, repair and operations (MRO) or maintenance, repair, and overhaul involves fixing any sort of mechanical, plumbing or electrical device should it become out of order or broken (known as repair, unscheduled, or casualty maintenance). It also includes performing routine actions which keep the device in working order (known as scheduled maintenance) or prevent trouble from arising (preventive maintenance). MRO may be defined as, "All actions which have the objective of retaining or restoring an item in or to a state in which it can perform its required function. The actions include the combination of all technical and corresponding administrative, managerial, and supervision actions."

MRO operations can be categorised by whether the product remains the property of the customer, i.e. a service is being offered, or whether the product is bought by the reprocessing organisation and sold to any customer wishing to make the purchase (Guadette, 2002). In the former case it may be a backshop operation within a larger organization or smaller operation.
