A power feeder bolts to a spindle moulder, circular saw or planer and drives the stock past the cutter at a set speed, so the feed rate never varies and the operator's hands stay clear of the tooling. This category holds 5 power feeders from HOLZMANN and NETMAK: three- and four-roller HOLZMANN heads with four or eight feed speeds, and NETMAK single-wheel and four-wheel units for template and straight work. Feeders are matched to the host machine and supplied by quotation.

How to choose a power feeder

Choose a power feeder by the shape of the work first and by feed speed second. Straight stock through a spindle moulder, a circular saw or a planer wants a multi-roller head that holds the board down and against the fence for the whole pass; curved work wants a single wheel that can follow a template instead of fighting the arc. All five feeders here do the same core job: the feeder drives the stock past the cutter at a constant rate, so the finish stops depending on how steadily the operator pushes, and hands never approach the tooling.

Roller count follows part length

Roller count is decided by part length. Three-roller heads cover most workshop runs, where the board is long enough that two rollers are always in contact: the HOLZMANN SF324N carries three 80 x 30 mm rollers, the HOLZMANN SF344N-8 three 120 x 60 mm rollers. Four-roller heads keep a longer stretch of board driven from entry to exit, which long mouldings and continuous through-feed need; the HOLZMANN SF444N-8 is 60 kg net in a 770 mm package against 56 kg and 560 mm for the SF344N-8, and the NETMAK ST-4 drives four 110 x 50 mm wheels at 80 kg. The NETMAK ST-1 exists for the opposite reason: one 110 x 50 mm wheel, 60 kg and 460 mm wide, so curved parts can ride a template.

Feed speed shows in the finish

Feed speed is the setting the surface will show. The HOLZMANN SF324N offers four speeds – 5, 5.6, 8 and 11 m/min – enough for straightforward moulding and ripping in one or two species. The eight-speed SF344N-8 and SF444N-8 span 3.5 to 34 m/min, so one head crawls through a deep hardwood profile and then runs ripped softwood out quickly. The NETMAK ST-1 and ST-4 are geared across four ranges from 4-6 m/min upward, the ST-1 reaching 20-30 m/min. A wide speed range earns its cost where species and profiles change often.

Power supply: three-phase, with one exception

Power supply narrows this page fast. The HOLZMANN SF324N is the only feeder catalogued in a 230 V version as well as 400 V, on a 260 W S6 (185 W S1) motor, which makes the SF324N the option for a small shop with no three-phase supply. The SF344N-8 and SF444N-8 are 400 V machines on a 1050 W S6 (750 W S1) drive, and the NETMAK ST-1 and ST-4 run a 1-1.15 HP motor. Confirm the voltage version in writing on the quotation.

Space, mounting and extraction

A power feeder takes no floor space of its own but changes the working envelope around the machine it sits on: infeed and outfeed clearance has to be measured for the longest board, not for the machine. Weight is carried by the column and the machine table – 35.78 kg for the SF324N, 56 kg and 60 kg for the HOLZMANN eight-speed heads, 60 kg and 80 kg for the NETMAK ST-1 and ST-4. Extraction remains the host machine’s responsibility, but a feeder turns intermittent cutting into continuous cutting, so size the extractor for a machine that now runs without pauses.

What to budget beyond the feeder

Budget the mounting arrangement and the wear parts alongside the feeder. Rubber rollers and wheels are consumable and harden with age; the host machine may need a base plate or drilling for the column; and the cutter block, saw blade or moulding tooling underneath is a separate line. Ask for mounting, spare rollers, delivery and installation to be itemised on the quotation.

როგორ ავირჩიოთ

Three-roller head (SF324N, SF344N-8): Standard straight runs where the board is longer than the roller train; the lighter head loads the machine table and column less.
Four-roller head (SF444N-8, ST-4): Long mouldings and continuous through-feed: four driven contacts keep the board under drive end to end, at 60 kg and 770 mm long, or 80 kg and 600 mm wide.
Single wheel (NETMAK ST-1): Curved and shaped parts run against a template on a spindle moulder - one 110 x 50 mm wheel follows the arc where a wheel train would fight it.
Four speeds vs eight speeds: Four speeds of 5-11 m/min on the SF324N suit one or two species; 3.5-34 m/min on the SF344N-8 and SF444N-8 covers deep hardwood profiles and fast softwood ripping on one head.
260 W vs 1050 W drive: The 260 W S6 SF324N is sized for light sections on a small moulder; the 1050 W S6 SF344N-8 and SF444N-8 push thick hardwood without dropping speed.
230 V availability: Only the SF324N is catalogued in 230 V as well as 400 V. Every other feeder on this page assumes a three-phase supply is already in the shop.
Head weight 35.78-80 kg: The column and the host machine's table carry the whole head, so check the machine before choosing the 80 kg ST-4 over the 35.78 kg SF324N.
Roller size 80 x 30 mm vs 120 x 60 mm: Wider, larger rollers spread grip over more surface on rough or resinous timber; the 80 x 30 mm rollers of the SF324N suit small, clean sections.

ხშირად დასმული კითხვები

How do I choose between a three-roller and a four-roller power feeder?

Choose between three and four rollers by part length. A three-roller feeder such as the HOLZMANN SF324N or SF344N-8 is enough whenever the board is long enough to keep two rollers in contact throughout the cut, which covers most workshop work. A four-roller feeder - the HOLZMANN SF444N-8 or the NETMAK ST-4 - keeps a longer stretch of the board driven and is the choice for long mouldings and continuous through-feed. The SF444N-8 costs you 4 kg more head weight and 210 mm more length than the SF344N-8 for that extra contact.

Can a power feeder run on single-phase 230 V power?

One power feeder on this page is catalogued for 230 V: the HOLZMANN SF324N, which is published in both a 400 V and a 230 V version on a 260 W S6 (185 W S1) motor. The HOLZMANN SF344N-8 and SF444N-8 are 400 V machines on a 1050 W S6 drive, and the NETMAK ST-1 and ST-4 carry a 1-1.15 HP motor. If your workshop has no three-phase supply, state that in the enquiry so the quotation is issued for the correct voltage version.

How much space and extraction does a power feeder need?

A power feeder needs no floor area of its own, because the feeder mounts on a column at the host machine, but it does need infeed and outfeed clearance measured against the longest board you intend to run rather than against the machine. Extraction stays with the host machine; the change a feeder brings is that cutting becomes continuous rather than intermittent, so the extractor and the chip bin should be sized for a machine that no longer pauses between boards.

Which machines can these power feeders be fitted to?

Power feeders on this page are made for spindle moulders, circular saws and planers - the NETMAK ST-4, for example, is listed for spindle moulders, surface planers and tilting-arbour circular saws. What decides the fit in practice is the host machine's table, the mounting position and whether the table can carry a head of between 35.78 kg and 80 kg. Send the make, model and table dimensions of the machine with your enquiry and the feeder will be matched to it before quotation.

What determines the cost of a power feeder?

The cost of a power feeder is driven by roller or wheel count, motor size, the number of feed speeds and the voltage version - a four-roller 1050 W eight-speed head sits well above a compact four-speed 260 W unit. On top of the feeder itself, the quotation should cover the mounting arrangement on your machine, any spare rubber rollers, delivery to your site and installation and setting. Ask for these to be itemised so you are comparing installed cost rather than head price.

Do I still need tooling and guarding if I fit a power feeder?

Yes - a power feeder replaces hand feeding, not tooling or guarding. The cutter block, saw blade or moulding knives on the machine below the feeder are a separate purchase and a separate line on the quotation, and the machine's own guards and hold-downs stay in use. Rubber feed rollers and wheels are wear parts as well, so plan a spare set into the first order rather than waiting for the originals to harden.
