Leisheng 34-Hole Adjustable Iron Ring Binding Machine for A4 Documents

Binding reports, manuals, and presentations in an office or print shop demands a reliable machine that handles repeated punching without jamming. The Leisheng 34-hole full drawing knife binding machine is designed for A4 paper (under 30cm) and works with double iron rings. With capacity to punch 15 sheets of 80gsm paper in one pull and bind stacks up to 130 sheets, it suits moderate-volume binding tasks. Its solid two-handle mechanism and adjustable margin settings give you control over document alignment, making it a practical choice for schools, graphic shops, printing houses, and conference rooms.

Features and Construction

The machine combines a metal chassis with a full drawing knife that cuts 34 square holes cleanly through paper. Its 3:1 pitch configuration (34 holes) is best for thinner documents, while a 2:1 version (23 holes) is available for thicker stacks. The handles are solid for consistent manual punching.

Punching Mechanism

The full drawing knife cuts 34 square holes (4x4mm each) across the paper width. Pulling the solid handle once punches up to 15 sheets of 80gsm A4 paper. The three-position margin adjuster (3mm, 5mm, 7mm) lets you set the distance from the paper edge to the hole centres, so you can align the binding strip to suit the document design.

Binding Capacity and Ring Compatibility

After punching, the machine can bind documents up to 130 sheets thick using double iron rings with diameters from 4.8mm to 15.9mm. The 34-hole pattern matches 3:1 pitch ring strips, which are commonly available. Ensure the ring size chosen fits the stack thickness: thinner rings for fewer sheets, larger rings for thicker ones.

Build and Dimensions

The machine measures 470x200x310mm packed and weighs 9.9kg gross (9.1kg net). Its compact footprint fits on a standard desk or binding station. The black finish is practical for a workshop or office environment where minor scuffs are less noticeable.

Uses and Placement

Leisheng binding machines are designed for environments where documents need frequent, consistent binding. The manual operation requires no electricity, so it can be placed anywhere with enough desk space.

Graphic Shop or Print House

For small print runs, the ability to punch 15 sheets at once keeps workflow moving. The adjustable margin enables neat alignment for presentation covers. Bind up to 130 sheets for booklets, catalogues, or training handouts.

Office and School Use

In an office, the machine is suitable for binding monthly reports, meeting packs, and policy manuals. Teachers can bind lesson plans or student handouts. The manual handle is quiet enough for a shared workspace compared to electric models.

Small-Scale Conference or Event

For events that require bound agendas or programmes, this machine can produce small batches quickly. No warm-up or power source is needed, making it portable to a different room if required.

Benefits and Buying Value

Choosing a manual binding machine over an electric one saves cost and avoids power constraints. The 34-hole 3:1 configuration is widely compatible with common double iron ring supplies.

Cost-Effective Operation

No electricity is required, so running costs are limited to consumables (double iron rings and paper). The machine itself is a one-time purchase with durable metal construction.

Consistent Hole Alignment

The full drawing knife ensures all 34 holes are cut simultaneously, giving even spacing across the paper edge. This reduces misaligned holes that can cause page tear-out when turning.

Why Choose This Product

For a small office, print shop, or school needing to bind A4 documents with iron rings, this Leisheng machine offers a straightforward manual solution with adjustable margin, 15-sheet punch capacity, and 130-sheet bind capacity. The 3:1 pitch is best for thinner documents, keeping consumable costs predictable.
